　　报告人简介： 

　　Donglin Jiang obtained his PhD from The University of Tokyo in 1998. He then began his academic career as an assistant professor at the University of Tokyo and was involved in developing functional polymers based on dendritic architecture until 2000 when he was appointed as the group leader of the JSTERATO. In 2005, he moved to the Institute for Molecular Science, National Institutes of Natural Science. Now he is a professor of Japan Advanced Institute of Science and Technology His current research interests include (1) synthesis, and (2) the photofunctional and electronic properties of COFs and conjugated microporous polymers (CMPs). 

　　报告摘要： 

　　Two-dimensional covalent polymers and organic frameworks are a class of crystalline polymers that enable the incorporation of organic building blocks into periodically aligned primary and high-order structures. In recent years, we have explored the design principle, synthetic reactions, structural diversity, functional design and materials applications. One significant feature is that the merge of covalent bonds and noncovalent interactions enables the precise control over primary and high-order structures. The geometry-directed covalent bonding enables the growth of two-dimensional atomic layer in which the primary-order structures are precisely controlled. The noncovalent π-π interactions guided by the total crystal stacking energy encode the ordered primary-order structure into high-order structures to construct periodically aligned polymer skeletons and nanosized unidirectional channels. In this seminar, I will discuss the chemistry, opportunity and challenges of COFs.
