课程介绍
报告摘要:Robust conjugated two- and three- dimensional organic network structures have attracted immense interest due to theirunusual electronic, optoelectronic, magnetic and electrocatalytic properties. In addition, their tunable structures and propertiespromise to offer many opportunities in various applications. However, even after years of intensive exploration of dimensionalorganic materials in science and technology, facile and scalable methods capable of producing fused-aromatic based stablenetworks with uniformly decorated heteroatoms with/without holes remain limited. To overcome these issues, stable organicnetwork structures have been designed and synthesized. They have uniformly distributed heteroatoms, holes with heteroatomsand transition metal nanoparticles in the holes. The structures were confirmed using various characterization techniques,including scanning tunneling microscopy (STM). Based on the stoichiometry of2D layered structures, they were, respectively,designated C,N, C,N, C,N, and M@C,N (M = Co, Ni, Pd, Pt, Ru). Their electronic and electrical properties were evaluatedby electrooptical and electrochemical measurements along with density-functional theory (DFT) calculations. Furthermore,robust three-dimensional (3D) cage-like organic network structures have also been constructed and they show high sorptionproperties. The results suggest that these newly-developed 2D and 3D organic networks offer greater opportunities, fromwet-chemistry to device applications. 报告人简介:Jong-Beom Baek is a professor/director at the School of Energy and Chemical Engineering/Center forDimension-Controllable Organic Frameworks, Ulsan National Institute of Science and Technology (UNIST), SouthKorea. After receiving his Ph.D. degree from Polymer Science, University of Akron (USA, 1998), he joined theWright- Patterson Air Force Research Laboratory (AFRL). He returned to his home country to take up a position as anassistant professor at Chungbuk National University in 2003, before moving to UNIST in 2008. His current research interestsinclude the syntheses of dimensional high-performance organic network structures and the chemical modifications ofcarbon-based materials for multifunctional applications including energy conversion and storage. He has authored andco-authored over 1 80 peer-reviewed publications in the areas. And also, he has registered and filed over 50 international anddomestic patents. Some of them have been transferred to industry for commercialization and started his own companies.
