Abstract

Second-order NLO characteristics of thin films based on model epoxy amine oligomers with 4-amino-4'-nitroazobenzene chromophore in the main chain, containing hydroxyl and methacryloyl groups, CFAO and CFMAO, respectively, are determined. Synthesized polymers possess high content of chromophore fragments and have good film-forming properties, which allowed one to cast homogeneous films of 200-400 nm thickness. The presence of reactive groups in the monomer units makes it possible to use cross-linking of polymer matrix to preserve the chromophores orientation order achieved in the course of corona poling and to provide relaxation stability of the second-order NLO response. Rather high values of the nonlinear optical coefficients estimated by second harmonic generation technique allow one to consider these epoxy amine polymers as promising candidates for the construction of cross-linked polymer matrices with long-term stability of the quadratic NLO response at elevated temperatures.
