Cluster-based hybrids

Investigation of the materials properties of the cluster-based hybrid polymers is in its infancy, and the properties of the new hybrid polymers are far from being exploited. We have seen two clear trends in the materials properties of inorganic-organic hybrid polymers prepared by polymerization of metal oxo clusters with organic comonomers. They depend on the portion of incorporated cluster and, surprisingly, also on the kind of incorporated cluster. ...

Approaches to the formation of three new types of micro-porous materials that complement zeolites will be discussed. In each case, whether metal coordination polymers, metal-linked ceramic oxide clusters, or new hybrids containing both coordination and ceramic components, engineering of the Secondary Building Unit (SBU) is of critical importance. Successful examples of these approaches include the first thermally stable 3-D micro-porous coordination polymer with chemical functionalizability [Cu3(TMA)2(H20)3] , as well as a 3-D micro-porous cluster based material [V,2B18O60H8(Cd(en)(H2O) 3]". ...
