Organic based optoeletronics have become increasingly important, not only from the basic research standpoint, also from the commercial perspective. Tremendous progress has been made in the past decades, which have led to a few commercial successes (e.g., organic light emitting diodes).
Both small organic molecules and polymers have been used as the key components for organic based optoelectronics. In this talk, I will try to briefly discuss our research progress in two subfields of organic based optoelectronics: molecular electronics, and polymer solar cells. In molecular electronics, we have been applying nanotransfer printing (nTP) to construct metal-molecule-metal junctions, which serve as a versatile platform to investigate the electron/spin transport behaviors of organic molecules, from insulating alkanes to conjugated oligomers. In polymer solar cells, we have been molecularly engineering conjugated polymers to achieve highly efficient bulk heterojunction solar cells. A few specific examples will be discussed to highlight the comprehensive approaches we have employed to elucidate the fundamental underlying principles.

Dr. Wei You obtained his BS from University of Science and Technology of China in 1999. He graduated with his PhD from the University of Chicago in 2004 with Professor Luping Yu, and finished his postdoctoral training at Stanford University in 2006 with Professor Zhenan Bao. In July 2006, Dr. You joined the University of North Carolina at Chapel Hill as an Assistant Professor in Chemistry, and was promoted to the rank of Associate Professor in 2012 when he also started serving as the Associate Chair for Research in the Chemistry Department. He has published over 60 papers in leading journals such as Nature Photonics, JACS, Angew. Chem., Int. Ed., Macromolecules, Advanced Materials, among others, and has been an Associate Editor for Polymer Chemistry (RSC) since July 2013. He has received DuPont Young Professor Award (2008), NSF CAREER Award (2010), Camille Dreyfus Teacher-Scholar Award (2011), Tanner Award for Excellence in Undergraduate Teaching (2011), CAPA Distinguished Junior Faculty Award (2012), and Ruth and Phillip Hettleman Prize for Artistic and Scholarly Achievement (2013). His group is currently investigating organic solar cells, molecular spintronics/electronics and devices, bio-inspired materials for biomedical applications, and new polymerization methodologies.
