Onion-shell Metal-organic Polyhedra (mops): A General Approach To Decorate The Exteriors Of Mops Using Principles Of Supramolecularrnchemistry

摘要

The design and construction of complex supramolecular architectures requires an understanding of how to control arrangements of noncovalent forces between multiple components to allow functionalities to be expressed. In this context, metal-organic polyhedra (MOPs) are attractive platforms to present surface-exposed organic groups in synthetic supramolecular chemistry. These capsular assemblies form via coordination-driven self-assembly of metal ions with organic subunits of predefined geometries. Much attention has focused upon inner cavities of MOPs to elucidate behaviors of guests. Comparatively little attention, however, has been paid to develop the exteriors, which could enable these cages to interact selectively with their environments and deliver their contents.
