Summary
The title polymer was prepared by the reaction of poly(4-formylstyrene) with 4-nitrophenylhydrazine. The polymer is amorphous and possesses a glass transition temperatureT g=230 °C. It crosslinks both thermally and by UV-irradiation and forms dense networks when heated aboveT g. All these properties make the polymer suitable for a stable poled system. However, a quite rapid thermal decay (bleaching) of the bound chromophore precludes the material from using in nonlinear optics.
