Preparation of osmium(II)-centered star-shaped polymer by the coordination of 2,2’-bipyridyl-terminated poly(oxyethylene) with osmium ion



Os(II)-Centered star-shaped polymer was prepared by the coordination of 2,2’-bipyridyl-terminated poly(oxyethylene) (bpy-POE) with osmium ion. The complexation of polymer ligand with metal ion proceeded as efficiently as that of the low molecular weight ligand. This methodology can easily be extended to various combinations of transition metal ion and polymer ligand. For example, we plan to design a starshaped polymer with a polynuclear Ru(II)-Os(II) bimetallic complex10 at the center core, thus creating a new class of photofunctional materials.
