Abstract
Two-dimensional covalent polymers and organic frameworks are a class of crystalline polymers that enable the incorporation of organic building blocks into periodically aligned 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.
Background
Donglin Jiang obtained his Ph.D. degree at the University of Tokyo in 1998. He then began his academic carrier 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 Japan Science and Technology Agency (JST), the Exploratory Research for Advanced Technology (ERATO) project on Aida Nanospace. In 2005, he moved to the Institute for Molecular Science, National Institutes of Natural Science as an associate professor to start his independent laboratory. In 2016, he moved to Japan Advanced Institute of Science and Technology as a full professor. He joined the Department of Chemistry at the National University of Singapore as a tenured full professor in 2018. His current research interests include two-dimensional covalent polymers and frameworks, including their chemistry, physics, and materials. In 2005 and 2009, he was awarded as a researcher for the JST PRESTO projects. He received the Wiley Award 2006 of the Society of Polymer Science, Japan, the Young Scientists’ Prize 2006 from the Commendation for Science and Technology by the Minister of Education, Culture, Sports, Science and Technology, Japan, and the 34th Chemical Society of Japan Award for Creative Works (2017).
