| Metal-directed self-assembly has been widely used to construct supramolecular systems such as grids, helicates, boxes, and cylinders. Compared to covalently-bonded organic counterparts, metal-organic supramolecules can be assembled with much ease and higher efficiency. The incorporation of metal centers can also impart novel functionalities such as host-guest recognition, inclusion, catalysis, and fluorescence sensing. Among many metal-organic supramolecular systems, the construction of molecular squares based on metallo-corners with ~90 º angles and linear bridging ligands has proven to be the most reliable strategy. We envision that the incorporation of axially chiral bridging ligands into molecular squares could lead to enzyme-like chiral supramolecular systems exploitable for enantioselective recognition, sensing, separation, and catalysis. I would like to present in this talk our recent results on the rational design and synthesis and detailed characterization of a variety of nanoscale chiral metallocycles, and preliminary exploration of their applications in chiral sensing. |
