Organometallic groups, polymer-bound

Pyrolysis products from organometallic phosphazenes can give nano-structured materials. Mixtures of AuCllPPhs) and poly[2,2 -dioxy-l,l -biphenylphosphazene] were pyrolyzed by heating the sample at 10 °C/min. to 800 °C, which was held for 2 hours under a flow of air. Characterization of the products by X-ray diffraction revealed a nanostructured Au material. Additional experiments were performed with metal centers directed bound to the phosphazene substrate. Structure (43) shows a phosphazene linear polymer substituted with 2,2 -biphenol and 4-hydroxyphenylacetonitrile pendant groups, with ruthenium coordinated to the terminal cyano groups.
