Abstract : Synthetic efforts toward novel NLO and piezoelectric polymers are described. NLO-phores are incorporated in the main chain of a polymer with all the dipoles in the same direction by polycondensation of AB-monomers. The polymers containing p-alkoxy-a-cyanocinnamate units in the backbone show cooperative enhancement of SHG in solution. For comparison, p-thio-a-cyanocinnamate is incorporated in the main chain and in the side chain of polymers, Novel potentially piezoelectric polymers synthesized include polymers containing multi-cyanocyclobutyl or -cyclopropyl groups and acrylonitrile copolymers.
