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.
About the Speaker:
Donglin Jiang obtained his Bachelor’s degree from Zhejiang University and his Ph.D. from the University of Tokyo in 1998. He began his academic carrier as an assistant professor at the University of Tokyo, and was involved in developing functional polymers based on dendritic architectures 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 (JAIST) as a full professor. In 2018, he joined the Department of Chemistry, Faculty of Science, National University of Singapore as a tenured full professor. His current research interests include two-dimensional covalent polymers and frameworks, including their chemistry, physics, and materials.
