New polymers were synthesized with discrete conjugated hydrocarbon segments alternating with flexible spacer groups. These processable polymers were designed for third-order nonlinear optical and conductivity studies for comparison with "fully-conjugated" polymers. The present materials contain distyrylbenzene or diphenylbutadiene units and have the advantages of solubility and melt processibility over "fully-conjugated" systems such as poly(acetylene). They were found in degenerate four-wave mixing experiments to have third-order optical susceptibilities in the range of 3 × 10-12 esu. These values are within an order of magnitude of the χ(3) value reported for unaligned poly(phenylenevinylene). Electrical conductivity measurements using I2 and H2SO4 dopants, however, provided materials with conductivities from 2 × 10-5 to 7 × 10-5 × 10-5 S/cm, far lower than poly(phenylenevinylene).
