Second-order nonlinear optical active polymethacrylate and polyester containing a methylsulfonylbenzothiazole azo chromophore

We synthesized the second-order nonlinear optical (NLO) copolymers for stud ying the effect of temperature on the temporal stability of the electro-opt ic effect. Heterocyclic azo chromophore was synthesized to be anchored to m ethacrylate and naphthalate polymer backbone. The decaying behavior of the electro-optic response was traced at different temperatures. The rates of r elaxation were considered based on the difference in the polymer structure.
