　　报告内容摘要：

　　Using polycondensation reaction of boronic acid with phenol, a triphenylene/pyrene-based 2D macromolecule (TP-COF) from triphenylene and pyrene monomers was synthesized. TP-COF is highly luminescent, harvests a wide wavelength range of photons and allows energy transfer and migration. Based on these findings, Jiang’s group targeted on the synthesis of photoconductive 2D macromolecule based on the self-condensation of pyrene diboronic acid. PPy-COF harvests visible light and triggers photocurrent generation with a quick response to visible light irradiation, allows repetitive switching of photocurrent without deterioration, and displays a large on–off ratio.

　　报告人简介：

　　Donglin Jiang obtained a Ph.D. in polymer chemistry from The University of Tokyo in 1998. He then became an academic carrier as assistant professor at The University of Tokyo and had been involved until 2000 in the development of functional polymers based on dendritic architecture. In 2000, he was appointed as a group leader of the JST ERATO Aida Nanospace project. In 2005, he moved to Institute for Molecular Science, National Institutes of Natural Sciences as associate professor. His current research interests include (1) two-dimensional polymers and organic frameworks and (2) conjugated microporous polymers. In 2005 and 2009, he was selected as a researcher of the JST PRESTO projects on “Structure Control and Function” and “Photoenergy conversion systems and materials for the next generation solar cells”. He received SPSJ Wiley Award 2006. He received The Young Scientists' Prize 2006, The Commendation for Science and Technology by the Minister of Education, Culture, Sports, Science and Technology, Japan.
