Abstract

We synthesized the second-order nonlinear optical (NLO) copolymers for studying the effect of temperature on the temporal stability of electro-optic effect. Heterocyclic azo chromophore was synthesized to be bound to methacrylate and naphthalate polymer backbone. Particularly, amino methylsulfonylbenzothiazole was employed to prepare the azo chromophore. Second harmonic generation can give us the relationship between the second harmonic signal and sample temperature during corona poling. The decaying behavior of second harmonic signal was traced at different temperature that is in the vicinity of the glass transition temperature.
