Functional materials with large nonlinear optical (NLO) activities are of great interest because of their vast applications in optoelectronic technology, such optical data storage. Because of their good processability and chemical resistance, NLO polymers are more attractive compared with the traditional inorganic materials. In the developments of NLO polymers, stabilization of electrically-induced dipole alignment is one of important criteria. A polyurethane matrix forms extensive hydrogen bonding between urethane linkages, with increased rigidity preventing the relaxation of induced dipoles. Physically cross-linked systems via hydrogen bonds have the advantages such as homogeneity and good processability. In this work we prepared novel polyurethane containing nitrothiazolylazoresorcinoxy groups as NLO chromophores, which constitute parts of the polymer backbone. After confirming the structure of the resulting polymer, we investigated its properties. |
