백종범 UNIST Stable organic network polymers have been designed and synthesized. They have uniformly distributed heteroatoms, holes with heteroatoms and transition metal nanoparticles in the holes. Their network structures were confirmed using various characterization techniques, including scanning tunneling microscopy (STM). Based on the stoichiometry of 2D layered network polymers, they were, respectively, designated C2N, C3N, C4N, and M@C2N (M = Co, Ni, Pd, Pt, Ru). Their electronic and electrical properties were evaluated by electrooptical and electrochemical measurements along with density-functional theory (DFT) calculations. Furthermore, robust 3D cage-like organic network polymers have also been constructed and they show high sorption properties. The results suggest that these newly-developed 2D and 3D organic network polymers offer greater opportunities, from wet-chemistry to various device applications. |
