Abstract

Electron donor and acceptor substituted poly(2‐methoxy‐5‐methylsulfinyl‐1,4‐phenylenevinylene) (PMMSPV) and a series of copolymers containing 1,4‐phenylenevinylene (PV) units were synthesized via the water‐soluble precursor pathway and cast into films. The electrical conductivity of FeCl~3~‐doped PMMSPV was 1.5 × 10^−4^ S ċ cm^−1^ and the copolymers showed conductivities in the range of 10^−4^ ∼ 10^−1^ S ċ cm^−1^ depending on the copolymer compositions. The second‐order nonlinear optical coefficient of PMMSPV was obtained with second harmonic generation method. The measured d~33~ value was 1.5 pm/V and gave no decay at 100°C over 40 d.
