Preparation and property of a novel soluble oxadiazole-containing functional polyacetylene

A novel high molecular weight functional polyacetylene bearing oxadiazole group as a pendant, poly{4-[2-(4-octoxyphenyl)-1,3,4-oxadiazolyl]-benzenyloxypropynylene}, was synthesized by [Rh(nbd)Cl]2-Et3N catalyst. The polymer was soluble in common organic solvents such as CHCl3 and THF. The structures and properties of monomer and polymer were characterized and evaluated with FTIR, NMR, UV, TGA, GPC, and CV, respectively. The results show that the polymer possesses high thermal stability and well electron-injection property.
