报告内容简介:
Chemists are often inspired by the spontaneous and precise assembly of multiple protein subunits into giant well-defined functional superstructures. Metal-directed coordination self-assembled systems offer a controllable platform on a molecular level toward mimicking such biological process. Using this strategy, a series of giant host molecules have been successfully synthesized and characterized, including an unprecedented spherical M24L48 rombicuboctahedral nano-cage. Molecular level studies on these artificial multi-component self-assembled systems offers mechanistic insights into the massive biological self-assembly phenomena. Moreover, these artificial supramolecular hosts with confined inner space served as nanovessels for highly selective and efficient catalytic transformations. In this talk, we will discuss the design principles for the metal-directed coordination self-assembly, the reversible structural modulation based on a post-synthetic modification method, along with the enzymatic catalysis using a supramolecular M4L6 tetrahedral cage.
