Regioregular Poly[2,5-bis(3-butyl-2-thienyl)tellurophene]: Synthesis and Characterization Aspects

This work reports on a novel, facile synthetic methodology into the tellurophene nucleus, which was applied in particular to the synthesis of the centrosymmetrical 2,5-bis(3-butyl-2-thienyl)tellurophene. Thereafter, oxidative polymerization of the monomer using iron (III) chloride afforded the regioregular poly[2,5-bis(3-butyl-2-thienyl)tellurophene]. Preliminary characterization aspects of the polymer are reported.
