T-Shaped Molecular Building Units in the Porous Structure of Ag(4,4'-bpy)-NO_3

摘要

The successful assembly of extended frameworks from molecular building units has yielded a remarkable class of materials having diverse architecture and functions. These include metal-organic solids with open frameworks having zeolite-like attributesand others having important electronic and magnetic properties. One of the simplest strategies employed in the production of such 3-D networks is schematically illustrated in Figure la,b, where open-framework diamond-like networks have been achieved by the addition copolymer-ization of either rod-like ligands~(5a-c) or metal clusters with tetrahedral metal ions.
