报告简介:Design and synthesis of porous structures with desired pore environments are essential for many applications, including separation, storage, sensing, and catalysis. Synthetically, metal-organic frameworks (MOFs) are crystalline porous materials that are highly tunable over their components and pore spaces. In addition, the presence of labile or reactive parts, including labile coordination bonds and dynamic covalent bonds, enables the precise tuning of the pore environments mainly at the molecular level.
His group focuses on the molecular pore engineering of MOFs, the design and synthesis of pores with desired individual and collective pore behaviors, which includes but not limited to the generation of various levels (microporous, “nanoporous”, mesoporous, and macroporous) of porosity, the creation of hierarchically porous structures, pore surface modification, pore combination, and pore partition. The structural modification of the intrinsic cavities within MOFs results in alteration of functionality, such as selective recognition and cooperative behavior. This structure-property relationship highlights the importance of constructing pore spaces with precisely controlled sizes and functionalities for various physical/chemical processes. The pore engineering methods are expected to be applicable to diverse MOFs, which shall provide essential guidance on synthesizing increasingly complex materials for various practical applications, especially for catalysis and bio-medical applications.
The seminar will cover synsthetic methods that have been developed in his lab such as “bridging-ligand substitution”, “ligand-fragment co-assembly”, “kinetic analysis and tuning”, “linker installation”, “linker labilization”, “cluster and linker metalation”, “linker migration”, “domino lattice rearrangement”, and “retrosynthetic design”.
