Rh(II)-based Metal-Organic Polyhedra

Metal-organic polyhedra (MOPs) are discrete porous materials which feature intriguing structures, well-defined cavities, and emergent functions. Among them, the recently developed Rh(II)-based MOPs represent a class of novel assemblies with robust structures, facile processabilities, and versatile functions thanks to the strong Rh-Rh bonds in the paddle-wheel units and the rich chemistries of the unsaturated Rh sites. These distinct characteristics make Rh(II)-based MOPs a prominent platform for the construction of functional materials with integrated discrete porosities. Therefore, in this mini-review, we highlight recent development and advances of Rh(II)-based MOPs as well as their applications from modular entities to supramolecular soft matter.
