A review. Prepn. techniques and characterization of the transition metal-contg. polymers (organometallic polymers) where the metal is bonded to at least one org. group through σ- and/or π-bonds. [on SciFinder(R)]

Over the past few decades, we have seen a growing interest in the development of various classes of metal-contg. polymers. While polymers are traditionally carbon-based materials that contain only a few other elements, organometallic polymers could incorporate almost all the other elements of the pe...

As functionalization of the polynorbornene backbone has shown to be a viable route towards altering the thermal and chem. properties of the resulting polymeric material, our focus has been on the prepn. of norbornene monomers contg. a side-chain consisting of a rigid mesogen and/or an aliph. spacer....

Photolytic demetallation of cyclopentadienyliron complexes was investigated. Effects of solvent nucleophilicity, counter anion, wavelength, and nature of the arene were studied. Initial results indicate a dependence on the wavelength of the light source as well as the duration of photolysis, with de...

The topic of metal-contg. polymers is reviewed with special emphasis on the need for polymeric materials for the 21st century and the role that metal and metalloid-contg. polymers will fill.
