title: Synthesis of oligothiophene-layered polymers.
abstract: Polymers with layered π-electron systems comprising bithiophenes and quaterthiophenes based on a xanthene skeleton have been synthesized by an iron-catalyzed oxidative coupling reaction. The polymers are well soluble in common organic solvents, and polymer thin films are readily obtained by a spin-coating or casting technique. The synthesized polymers exhibit good thermal stability, and their 10% weight loss temperatures are approximately 400 °C. These behaviors of the polymers suggest that they can be used as opto-electronic devices such as hole-transporting materials.
