Electron donor and acceptor substituted (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
FeCl3-doped PMMSPV was 1.5 x 10(-4) S . cm(-1) and the copolymers show
ed conductivities in the range of 10(-4) similar to 10(-1) S . cm(-1)
depending on the copolymer compositions. The second-order nonlinear op
tical coefficient of PMMSPV was obtained with second harmonic generati
on method. The measured d(33) value was 1.5 pm/V and gave no decay at
100 degrees C over 40 d.
