Mar. 18, 2013 ? University of Oregon chemists have synthesized organic molecular structures that move both positive and negative electrical charges -- a highly desired but often difficult combination to achieve in current efforts to create highly flexible electronic devices and other new-age technologies.
The research utilized a family of readily available and inexpensive hydrocarbons known as indenofluorenes to build molecular scaffolding for integrative circuitry. An indenofluorene-derivative framework, said co-author Michael M. Haley, head of the UO Department of Chemistry, offers more simplicity, flexibility and affordability than that available using many other hydrocarbon-based approaches.
Haley's lab in the UO's Materials Science Institute reported a linear version of the new molecular structure in the Journal of the American Chemical Society last June. For the new paper -- placed online in advance of regular publication in the ACS journal Organic Letters -- Haley's team manipulated that infrastructure into a more bent architecture and tested some of its fundamental optical and electronic properties.
Using organic molecules is helping materials scientists move beyond silicon semiconductor technology, said Aaron G. Fix, a doctoral student in Haley's lab and lead author of the new paper. "You don't need to lay the molecules on silicon. They can be laid on plastics and other materials, as long as you have the necessary metallic or graphite contacts," he said. "These new materials will allow for electronics that can take on stresses at levels traditional silicon, which is brittle, cannot handle. We will be able to make stretchable and bendable devices."
A lot of different materials can be used in organic electronic devices, Fix said. Most of them, he added, move positive charges well but not negative charges. "We are trying to fill that niche by developing materials that can do that well," he said.
Researchers pursuing devices utilizing organic semiconducting technology already are envisioning applications from roll-up computers to synthetic skin for robotic and prosthetic applications. Similar research done elsewhere with such approaches has surfaced in some smart phones and television screens.
"Specifically, we are doing research on transporting electrons using these indenofluorene materials for building integrated circuits for computers," said co-author Parker E. Deal, who worked in Haley's lab on both projects as an undergraduate chemistry major in the Robert D. Clark Honors College at the UO. "This is fundamental research in that these are new molecules that nobody has made before, and we are studying them to see how effective they are and how they may further our improvement of these materials to build cheap, flexible devices."
The project, Haley said, is "old-school chemistry" and uses no precious metals. These hydrocarbons, he said, are cheap and easily manipulated for creating artificial materials. "And we have shown that we are able to prepare the materials in gram quantities with good overall yields and excellent purity using methodologies that should work in large-scale production," he said.
Haley's team is about to work with an outside collaborator to test the new scaffolding in an electronic device. If successful, Haley said, work on the approach can move forward.
"This research by Dr. Haley and his team promises to open a whole new world of possibilities for scientists and innovators," said Kimberly Andrews Espy, vice president for research and innovation at the University of Oregon. "Researchers at the University of Oregon continue to solve today's challenges through the development of tools and technologies that will redefine our future."
The National Science Foundation supported the research (grants CHE-1013032, CHE-0923589 and OCI-0960354). Co-author Bradley D. Rose, a doctoral student, worked on both projects under the Emmanuil Troyansky Fellowship of the American Chemical Society.
Additional co-authors were graduate student Chris L. Vonnegut and Lev N. Zakharov of the UO-based Center for Advanced Materials Characterization in Oregon (CAMCOR).

MILWAUKEE (AP) ? Brandon Jennings glanced over and expected to see coach Scott Skiles on the end of the Milwaukee Bucks' bench. Instead, he saw Jim Boylan sitting in Skiles' old spot.
Jennings scored 29 points and the Bucks gave Boylan a win in his first game as coach with a 108-99 victory over the Phoenix Suns on Tuesday night.
"I'm just hooping," Jennings said. "It was weird looking on the end of the bench and he wasn't there. I'm sure I'll get over it soon. Jim's been here for four years. It'll be good sooner or later."
The Bucks parted ways with Skiles on Monday in what was called a mutual decision, and the Bucks tapped Skiles' top assistant Boylan as a replacement.
"I almost called Jim 'Scott' at one point," Jennings said. "But, hey, it's a business. I understand now. I've seen a lot."
Milwaukee's new head coach said before the game his top priority would be to get the Bucks playing well again after losing four consecutive games.
The Suns were a perfect opponent, playing poorly in the last few weeks with nine losses in the previous 10 games overall to go with a nine-game losing streak on the road.
"We can't play 40 minutes, 42 minutes or 38-minute games where we play pretty good and give ourselves an opportunity and then let it deteriorate away over a four- or five-minute period," Phoenix coach Alvin Gentry said. "That's kind of how our season has gone, really. We've just got to find a way to get better. The season is slipping away."
This is the second time Boylan has succeeded Skiles midseason. He took over the Chicago Bulls when Skiles was fired on Christmas Eve in 2007.
"I've been down this road before," Boylan said. "I won my first game against the Bucks when I was in Chicago, and it felt great. Feels great right now, too."
Jennings, who before the game said he was frustrated that he learned of the coaching change from Skiles himself instead of someone from the Bucks organization, made 9 of 15 shots and had nine assists.
"The main thing is I wasn't thinking," he said. "I was just, you know, taking whatever the defense gave me. I was able to find guys. Guys were making shots tonight."
Goran Dragic scored 21 points and Jared Dudley added 18 for Phoenix.
Larry Sanders had 10 points, eight rebounds, six blocks and three steals for Milwaukee. The Suns scored only 10 points in the paint in the second half as Sanders dominated defensively.
"Everything went down again," Marcin Gortat said of the second half. "Brandon Jennings, he just took it over, he started shooting 3s. We couldn't stop him."
The Bucks won despite an off-night from leading scorer Monta Ellis, who missed 14 of 19 shots and committed five turnovers. Ellis finished with 13 points after coming in with a 19.4 average.
Boylan made a couple of significant changes in his first game at the helm, inserting forward Ersan Ilyasova into the starting lineup and giving more minutes to rookie forward John Henson, the team's first-round draft pick.
Ilyasova had 12 points, six rebounds and four assists in 26 minutes. Henson had 12 points and 11 rebounds in 19 minutes.
"I like the way that looks right now," Boylan said of playing Henson and Ilyasova.
Milwaukee took control with a 12-3 run that spanned the end of the third and beginning of the fourth quarters. Beno Udrih had four points in the spurt and hit a 17-foot jumper with 8 minutes left to give the Bucks a 90-79 lead.
Phoenix pulled to 95-91 on a pair of free throws by Dragic with 3:49 left, but Henson scored on a dunk and Mike Dunleavy made a driving layup to extend the Milwaukee lead to 99-91 with 2:45 remaining. Phoenix never seriously threatened the rest of the game.
The Bucks used a 13-0 run, keyed by a pair of 3-pointers from Jennings and four points from Ilyasova, to open a 71-66 lead with 4:57 left in the third quarter.
Luis Scola's baseline jumper tied it at 71, but Ellis drove the lane for a basket that gave Milwaukee the lead for good, 73-71, with 3:34 left in the third.
Notes: Bucks GM John Hammond said before the game he and the team were talking about a contract extension. ... The ball stopped motionless at the back of the Phoenix rim ? not stuck ? with 9:24 to go in the second quarter, prompting wide grins from the Suns bench. Milwaukee won the ensuing jump ball. ... The teams meet again Jan. 17 in Phoenix.

Fire or tsunami damage to New Zealand's only oil refinery could easily?cripple domestic oil supplies with flow-on effects for freight, air?travel and tourism, says Air New Zealand.
The national carrier has made the comments in its submission on the?Ministry of Business, Innovation and Employment's (Mobie) review of the?country's oil security.
The company targets the Marsden Point Refinery near Whangarei as a?weak point in the domestic supply chain because it says its?off-loading wharf, pipelines, storage facilities and refinery are all?closely linked.
This "interdependence" makes the importing capability of the?facility vulnerable to a fire in the refinery, meaning imported jet?fuel supply would be likely to cease during a fire and for a time?while damage was repaired, the airline says.
"Refineries do catch fire ... Fires do happen in well run?refineries," it says in its submission.
Air New Zealand also says Mobie's report has understated the tsunami?risk to Marsden Point and work should be done to better understand the?potential impacts on the refinery and its wharves.
"Just because an event is one in 2500 years doesn't mean it can't?happen tomorrow."
The airline said lessons could be learned from the experience of?refineries along Japan's east coast which were affected by the 2011?tsunami.
In its own submission, Refining NZ says a major disruption to its?Marsden Point Refinery over an extended period could have an economic?impact of up to $400 million with ongoing costs.
The cost of a minor disruption, or one which does not completely stop?supply, could run to $6.5m a day.
However, Refining NZ backed its safety record, saying its annual rate?of unplanned downtime on key processing facilities was 1.3 per cent?for the year to February 2011, and it had recently achieved two million
hours' work without a lost time incident.
It said greater security of supply would result from further?investment in pipelines leading from Marsden Point to Auckland and in?development of the Wiri oil terminal in south Auckland.
But Air New Zealand has also submitted an idea to construct a new fuel?storage depot in west Auckland to supplement the existing Wiri depot,?which it says should be used only for jet fuel.
The Wiri terminal is operated by Wiri Oil Services Ltd (Wosl) - a?collective of the four major oil companies BP, Chevron, Mobil and Z?Energy - and judging by its own submission is planning to expand the
terminal and does not see a need for a separate depot.
Submissions from Wosl and Refining NZ cite the protection of land?around the Wiri terminal as a major concern, saying encroachment of?sub-divisions and other land uses could endanger the future use of
land for fuel storage.
Both companies believe new oil storage facilities, such as that?suggested by Air New Zealand, would be unnecessary and costly.
But Air New Zealand says the industry is not collectively acting "to?develop a coherent medium term strategy and undertake new investments?that have medium term benefits".
The fuel companies were unwilling to combine their fuel storage?facilities at Christchurch Airport despite encouragement from Air New?Zealand, says the airline's submission.

WASHINGTON (AP) ? President Barack Obama's choice of John Brennan to be the next CIA director hit a snag Tuesday as a Republican senator threatened to delay the nomination until the Obama administration provides answers on the deadly assault in Libya that killed the U.S. ambassador and three other Americans.
Sen. Lindsey Graham, whose opposition helped scuttle U.N. Ambassador Susan Rice's hopes of becoming secretary of state, said the Senate should not confirm any Obama nominee for the nation's top spy post until the administration elaborates on the attack on the diplomatic mission in Benghazi.
"My support for a delay in confirmation is not directed at Mr. Brennan, but is an unfortunate, yet necessary, action to get information from this administration," the South Carolina senator said in a statement. "I have tried ? repeatedly ? to get information on Benghazi, but my requests have been repeatedly ignored."
He added that the administration's "stonewalling on Benghazi" must end.
Graham did not explicitly say he would put a "hold" on Brennan's nomination, and his office declined further comment. However, his statement signaled that he would try to slow the nomination.
The White House dismissed the politicization of the issue and pressed for the Senate to act quickly and deliberately on Brennan's nomination.
"It would be unfortunate, I think, if in pursuit of this issue, which was highly politicized, the Senate would hold up the nomination of John Brennan to be director of the Central Intelligence Agency," White House spokesman Jay Carney told reporters.
An independent review board released an exhaustive report last month that found "systematic failures and leadership and management deficiencies at senior levels" of the State Department that led to inadequate security at the mission in Benghazi.
Secretary of State Hillary Rodham Clinton is likely to deliver her long-awaited testimony on Libya before the Senate Foreign Relations Committee on Jan. 22, although the State Department says the date hasn't been finalized.
Illness and a concussion delayed her congressional appearance in December, one of her last acts as secretary of state. Obama has nominated Sen. John Kerry, D-Mass., to replace Clinton after Rice withdrew her name from consideration.
In the weeks after the Sept. 11, 2012, attack that killed U.S. Ambassador Chris Stevens, Republicans criticized the administration for blaming spontaneous protests over an American-made, anti-Muslim video. They suggested the administration was trying to play down an act of terrorism leading up to the November election, even though Obama used that description in the days after the raid.
Graham and Sen. John McCain, R-Ariz., directed much of their ire at Rice, who said in a series of Sunday talk show interviews on Sept. 16 that the attack may have been a protest that got out of hand. Rice's widely debunked explanation was based on talking points from the intelligence community.
Graham said he wants answers on who changed Rice's talking points and deleted references to al-Qaida. He said lawmakers were told that the director of national intelligence deleted the references, then were told it was the FBI. Hours after a meeting with Rice in late November, Congress was informed that the CIA had changed the talking points.
"This ever-changing story should be resolved," Graham said. "It is imperative we understand who changed the talking points just weeks before a presidential election and why."
Graham, who is up for re-election next year, has been an outspoken critic of the administration on Libya.
Carney pointed out that Obama pressed for swift confirmation of his national security nominees when he announced the selections Monday, and the administration hopes there are no unnecessary delays. He noted that the FBI is continuing its investigation of the attack, the independent review board issued a scathing report and Obama wants to bring the perpetrators of the attack to justice.
"The president is focused on those issues, not what seems to be the continued political fascination with appearances on Sunday shows," Carney said.
Brennan was expected to have an easier time on the path to Senate confirmation than Chuck Hagel, Obama's choice to run the Pentagon. A handful of Republicans have announced opposition to their former GOP colleague, and several skeptical Democrats reserved judgment until Hagel explains his views on Israel and Iran.
The concerns about Hagel complicate his path to Senate confirmation but are not necessarily calamitous as the White House pushes for the first Vietnam War veteran and enlisted Army man to oversee a military emerging from two wars and staring at deep budget cuts.
Brennan, a 25-year CIA veteran, is expected to be hit with questions about torture and administration leaks of secret information at his hearing, but is widely expected to win Senate confirmation. Graham's demands on the Libya raid could stall the nomination.
Hagel has upset some Israel backers with his comment about the "Jewish lobby," his votes against unilateral sanctions against Iran while backing international penalties on the regime in Tehran and his criticism of talk of a military strike by either the U.S. or Israel against Iran.
He also upset gay rights groups over past comments, including his opposition in 1998 to President Bill Clinton's choice of James Hormel as ambassador to Luxembourg. He referred to Hormel as "openly, aggressively gay." Hagel recently apologized, saying his comments were "insensitive."
Those remarks and actions have created fierce opposition from some pro-Israel groups, criticism from some Republicans and unease among some congressional Democrats.
In an interview with the Lincoln (Neb.) Journal Star, Hagel said his statements have been distorted and there is "not one shred of evidence that I'm anti-Israeli, not one (Senate) vote that matters that hurt Israel."
During a trip to the Mideast, Sen. Bill Nelson, D-Fla., sought to reassure Israelis concerned about Hagel's nomination. Nelson, a member of the Armed Services Committee, said Hagel has a record of support for Israel.
Nelson said he discussed Hagel's nomination with Israeli Prime Minister Benjamin Netanyahu. He said the prime minister did not voice objections to Hagel.
Former Sen. Max Cleland, D-Ga., himself a wounded Vietnam veteran, said he thinks Hagel "has to clarify" his positions on issues like Iran and Israel.
But Cleland also said in an interview on "CBS This Morning" Tuesday that Hagel is battle-tested and ready for the challenges of a confirmation process, accusing the Nebraskan's critics of "swatting at nothing, shadow-boxing."
