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.
