Multicomponent Self-Assembly of a Nested Co_(24)@Co_(48) Metal-Organic Polyhedral Framework

摘要

Discrete high-symmetry coordination cages, some of which have recently been called metal-organic polyhedra (MOPs), represent one of the most fascinating classes of coordination compounds because of their intriguing host-guest chemistry associated with high and tunable porosity, as well as their aesthetic appeal. Furthermore, their formation can be regarded as a somewhat simplified version of the complex biological self-assembly process and as such they can serve as models for biosystems. More recent advances in the development of 3D metal-organic polyhedral frameworks (MOPFs), loosely defined here as a subset of MOFs constructed with MOPs as building blocks, have revealed an even greater level of complexity in the self-assembly of coordination polymers. These MOPFs have emerged as a growing new class of materials because of their remarkable structural characteristics (e.g., well-defined cavities) and potential applications in areas such as gas storage and separation, drug delivery, and catalysis.
