Synthesis of polythienylenevinylene copolymers bearing carbondithioate structures

A new type of thiophene-based copolymers bearing the carbondithioate groups were synthesized through Wittig–Horner reaction. Copolymers were characterized by elemental analysis, UV–Vis, and FT-IR. Conductivity of I2 doped copolymers ranges from 10−3 to 10−2 S/cm.
