Abstract

Employing the conventional second-order nonlinear optical (NLO) chromophore such as nitrostilbene derivative, we synthesized a polymer composed of poly CK-methylstyrene structure. New α-methylstyrene polymer containing piperazyl nitrostilbene in the side chain was designed and synthesized in an attempt to enhance both the electrooptic coefficient, and its temporal stability. The polymer showed the high glass transition temperature (Tg) implying better temporal stability of the second-order NLO property. This polymer film was corona-poled under 3.5 - 5 kV at the temperature which was either close to the Tg or higher than that. The electrooptic coefficient of this polymer was measured to be 23 - 28pm/V at 632.8 nm of He-Ne laser.
