Abstract
We report the synthesis, optical and electrochemical properties, as well as fabrication of light-emitting devices for a series of twistacenes and heteroacenes. Their structures, determined by X-ray crystallography, confirmed that these materials have twisted topology with torsion angles as high as 23.0°. These materials can emit blue, green and orange light. Organic light emitting devices using these materials as emitters have been fabricated. The results revealed that these materials are promising materials for high efficiency OLEDs. In addition, we also made a lot of N-substituted oligoacenes and their properties will be discussed in this talk.
CV for Dr. Qichun Zhan
Dr. Qichun Zhang obtained his B.S. at Nanjing University in China in 1992, MS in physical organic chemistry (organic solid lab) at Institute of Chemistry, Chinese Academy of Sciences (Prof. Peiji Wu/Daoben Zhu’s group, ICCAS, Beijing) in 1998, MS in organic chemistry (Prof. Fred Wudl’s group) at University of California, Los Angeles (USA), and completed his Ph.D. in inorganic chemistry at University of California Riverside (Prof. Pingyun Feng’s group, USA) in 2007. Then, he joined Prof. Kanatzidis’ group at Northwestern University as a Postdoctoral Fellow (Oct. 2007 –Dec. 2008). Since Jan. 2009, he joined Nanyang Technological University (NTU) as an Assistant Professor. Besides these, he also has three-year working experience in research institute of Nanjing Chemical Industry Co. (Aug. 1992 – Aug. 1995) and two-year’s research experience in ICCAS (Aug. 1998 – Jun 2000). He has published 91 papers and 4 patents. Some of his papers have been published in Nature Chemistry (2 papers), Angew. Chem. Int. Ed (2 papers), J. Am. Chem. Soc. (8 papers), ACS Nano, Chem. Comm., Adv. Funct. Mater, Small, Org. Lett., Chem. Mater., J Mater. Chem., Chem. Eur. J., Appl. Phys. Lett.; Nanoscale; Chem. Asian J. etc.
