报告题目:Synthesis, Characterization, and Applications of Larger N-heteroacenes

KeywordsN-heteroacenes, synthesis, characterization, application

Although it is very tedious and extremely challenging to experimentally obtain large acenes or N-heteroacenes (n≥10) with precise structure analysis due to their poor solubility and high reactivity, their unusual optical and electronic properties as well as their interesting spatial arrangement strongly encourage scientists to devote their efforts in this field. Currently, only five molecules with single crystal structure have been reported and three of them are from my group (Figure 1). At the meanwhile, structure-well-defined N-heteroacene with fifteen linearly-fused aromatic six-member rings from my group is a record now. In this talk, I will present our recent progress on the preparation of novel larger azaacenes (n≥10) and their possible applications.

Brief CV of Dr. Qichun ZHANG

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 School of Materials Science and Engineering at Nanyang Technological University (NTU, Singapore) as an Assistant Professor. On Mar 1st, 2014, he has promoted to Associate Professor with tenure and on Dec 1st, 2014, he became an adjunct Associate Professor at Division of Chemistry and Biological Chemistry, School of Physical and Mathematical Sciences, Nanyang Technological University. 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 received TCT fellowship in 2013 and lectureship from National Taiwan University in 2014. Currently, he is an associate editor of J. Solid State Chemistry, the Advisory board member of Materials Chemistry Frontiers, and the Advisory board member of Inorganic Chemistry Frontiers. Also, he is a fellow of the Royal Society of Chemistry. He has published > 250 papers and 4 patents (H-index: 51).
