Assymmetrically disubstituted ly(2-isopropoxy-5-methoxy-1,4-phenylene-
vinylene), PIMPV, was prepared in thin films via organic-soluble precu
rsor polymer method. These polymer films could be easily stretched up
to 7 times, and the drawn films of the PIMPV could be doped with FeCl3
and I2 to give conductivities of 26.9 and 11.3 Scm-1, respectively. T
he third-order nonlinear optical susceptibility of the polymer was det
ermined using third harmonic generation(THG) method at 1907 nm, fundam
ental wavelength. Measured chi(3) (-3omega: omega, omega, omega) value
was 3.7 x 10(-12) esu.
