Poly(2,5-dipropargyloxy-1,4-phenylenevinylene) (PDPPV) and its copolym
ers were prepared as thin films via the organic-soluble and water-solu
ble precursor routes. Elimination and crosslinking reactions could be
controlled by the temperature. Crosslinked PDPPV is stable up to 450 d
egrees C. The conductivity values of undrawn and drawn FeCl3-doped PDP
PV films are 5.0 x 10(-2) and 2.0 x 10(-1) S . cm(-1), respectively. T
he third-order nonlinear optical susceptibility, chi((3)), for the PDP
PV film was investigated by degenerate four-wave mixing (DFWM) techniq
ue at 602 nm wavelength, and found to be 2.3 x 10(-10) esu.
