[Aspuru-Guzik group list] CANCELLATION: Excitonics Seminar - Prof. Rachel A. Segalman

by rtavilla＠rle.mit.edu

Good Morning, Please note that this seminar is cancelled. Prof. Segalman's trip to the east coast has been postponed and therefore this seminar will be postponed. Thank you, Rita ----- Forwarded by Rita Tavilla/RLE on 10/13/2009 09:30 AM ----- Rita Tavilla 10/08/2009 01:24 PM To: excitonics-seminars(a)mit.edu cc: Subject: ANNOUNCEMENT: Excitonics Seminar - Prof. Rachel A. Segalman Center for Excitonics Seminar Series Announcement The Center for Excitonics invites you to join us at the next seminar of the 2009 series. Please forward this information on to others who might be interested in attending this and other center seminars. Title: Hierarchical Pattern Control in Semiconducting Polymers Presenter: Prof. Rachel A. Segalman Organization: Chemical Engineering Department University of California, Berkeley and Lawrence Berkeley National Laboratories Date: October 15, 2009 Time: 3:00 - 4:00pm Place: 34-401A Refreshments: Yes Center URL: http://www.rle.mit.edu/excitonics Seminar URL: http://www.rle.mit.edu/excitonics/segalman-101509.html Abstract While polymers hold significant potential as low cost, mechanically flexible, light weight large area photovoltaics and light emitting devices (OLEDs), their performance relies crucially on understanding and controlling the morphology on the nanometer scale. Two important materials constraints are responsible for the morphology challenges faced in these fields. The 10nm lengthscale of exciton diffusion sets the patterning lengthscale necessary to affect charge separation in photovoltaics. The imbalance of electrons and holes mobilities in most organic materials necessitates the use of multiple components in many device architectures. Both light emitting and photovoltaic devices rely crucially on crystal/grain structure for improved charge transport. These requirements for hierarchical patterning in large area, solution processed devices suggest that block copolymer strategies, previously employed for more classical, insulating polymer systems, may be very useful in organic electronics. The thermodynamics of these materials, however, is distinct from classical block copolymers due to the conformational asymmetry of a rigid, conjugated polymer chain. We have studied both the fundamental self-assembly of molecules of unusual shapes as well as applied these principles to bipolar molecules for photovoltaic and light emitting devices. We can use these molecular handles to control the orientation of the internal interfaces within the active layer of a device. In addition to our work on the internal interfaces of a device, I will also discuss efforts to understand the electrode interface where the discrete density of states of the molecule interact with the continuous states of the electrode. In particular, we have found that single molecule conductivity and thermopower measurements lend significant insight and suggest that organics may find new applications as thermoelectric energy generating devices. Bio Dr. Segalman is an Associate Professor of Chemical Engineering at UC Berkeley and Faculty Scientist of Lawrence Berkeley National Laboratories. She graduated from the University of Texas at Austin with a B.S. with Highest Honors in Chemical Engineering. While pursuing a Ph.D. with Ed Kramer at UC Santa Barbara, she developed a graphoepitaxial strategy for aligning arrays of block copolyme r spheres over distances previously unobserved. Further quantitative microscopic analysis of this nanometer scale patterning then led to fundamental discoveries as to the nature of ordering and melting on in two dimensions. Dr. Segalman then received a Chateaubriand fellowship to pursue research in Strasbourg, France in the group of Georges Hadziioannou studying the synthesis of conducting block copolymers. Her current research is focused on understanding the connection between morphology and properties in functional polymers. She has won numerous awards including: Alfred P. Sloan Fellow (2009); Presidential Early Career Award in Science and Engineering (PECASE, 2008), Lawrence Berkeley National Lab, Materials Science Division’s Young Scientist of the Year Award (2008); Mohr-Davidow Ventures Innovators Award (2007), Technology Review’s Top 35 Innovators under 35 years old (TR35-2007), 3M Untenured Faculty Award (2006-2008), Hellman Family Young Faculty Award (2007); National Science Foundation CAREER Award (2005); Intel Young Faculty Award (2004). She is also an Associate Editor of the Annual Reviews of Chemical Engineering and on the editorial advisory board for Macromolecules.

[Aspuru-Guzik group list] Neko Case

by Anna B. Shin

Anyone interested in seeing Neko Case in concert? She's performing at Wilbur Theatre on Tue 10 Nov. I'm getting my ticket at the box office sometime this week. Tickets are $35. If you want to listen to her music before you decide, check out her website: http://www.nekocase.com/music/ or you can borrow my CDs. David has them now. I have most of her albums except the most recent one Middle Cyclone and a couple others. Furnace Room and Fox Confessor are the best so check out those first. Star Witness is the BEST song ever.
