Abstract
We synthesized the crosslinkable second-order nonlinear optical (NLO) side chain copolymer for studying the effect of temperature on the electro-optic effect. Heterocyclic azo chromophore was synthesized to be bound to α-methylstyrene polymer backbone. Particularly, two electron-withdrawing groups were overlaid to enhance the dipole moment in one chromophore. The resistance and electric potential between the two electrodes was characterized with the temperature. Electro-optic signal and coefficient were investigated using the modified reflection technique. The temperature effect can be considered fully relating to the generation of electro-optic effect during poling. Time resolved study gave us much information how the electro-optic properties can be brought about.
