A novel polyester (4) containing dioxybenzylidenecyanoacetate group as a NLO-chromophore was prepared and characterized. Polyester 4 was soluble in common organic solvents such as acetone and DMSO. Polymer 4 showed thermal stability up to 280 degrees C in TGA thermogram with T-g value measured from DSC thermogram near 108 degrees C. The SHG coefficient (d(33)) of poled polymer film at the 1064 nm fundamental wavelength was around 3.54 x 10(-9) esu. The dipole alignment exhibited a thermal stability up to near Tg and no significant SHG decay was observed below 95 degrees C due to the partial main-chain character of polymer structure, which was acceptable for NLO device applications.
