There has been significantly growing interest in well-defined, covalent organic polyhedron (COP) molecules due to their unique 3-D structural features and potential applications in studying host-guest interaction, molecular separation, catalysis, etc. This talk will describe the successful synthesis of a series of structure-tunable, shape-persistent COPs via thermodynamically-controlled, dynamic covalent chemistry (DCC) with high efficiency. The porous COPs showed unprecedented high selectivity in adsorption of CO2 over N2 (up to 138/1), thus showing great promise in carbon capture applications. Covalent crosslinking of these COP molecules led to the formation of novel framework materials with ordered intrinsic porosity (cage-to-framework strategy). Their high chemical and thermal stability and great tunability in both pore volume and surface functionality represent great advantages. The structure-property relationship of this novel class of organic porous materials will also be discussed.
