Abstract

A poly(p-phenylenevinylene) derivative bearing conjugated side chains (polyCPV) was synthesized by Migita-Kosugi-Stille type coupling polycondensation reaction. This polymer contains phenylenevinylene units in both the main chain and the side chains. UV-vis absorption and fluorescence emission spectroscopies revealed a well-developed π-conjugation of the polyCPV. The absorption band of the polymer was extended to long wavelengths. A fluorescent emission maximum of polyCPV is located at considerably longer wavelengths than that of the conjugated side chain monomer. Electron spin resonance measurements of polyCPV confirmed generation of charge species in both the main chain and the side chains via iodine doping.
