A novel Y-type polyurethane 4 containing 5-methyl-4-{5-(1,2,2- tricyanovinyl)-2-thiazolylazo}resorcinoxy groups as nonlinear optical (NLO)-chromophores, which constituted parts of the polymer backbones, was prepared and characterized. Polyurethane 4 is soluble in common organic solvents such as acetone and N,N-dimethylformamide. It showed a thermal stability up to 250°C in thermogravimetric analysis thermogram and the glass-transition temperature (Tg) obtained from differential scanning calorimetry thermogram was around 118°C. The second harmonic generation (SHG) coefficient (d33) of poled polymer film at 1560nm fundamental wavelength was around 8.43 × 10-9esu. The dipole alignment exhibited a thermal stability even at 12°C higher than Tg, and there was no SHG decay below 130°C due to the partial main-chain character of the polymer structure, which is acceptable for nonlinear optical device applications.

A novel Y-type polyester 4 containing 5-methyl-4-{5-(1,2,2-tricyanovinyl)- 2-thiazolylazo}resorcinoxy groups as nonlinear optical (NLO) chromophores was prepared and characterized. Polyester 4 is soluble in common organic solvents such as acetone and N,N-dimethylformamide. It shows a thermal stability up to 250°C from thermogravimetric analysis thermogram with a glass-transition temperature (Tg) obtained from differential scanning calorimetry thermogram of around 94°C. The second harmonic generation (SHG) coefficient (d33) of poled polymer film at 1064nm fundamental wavelength is 8.12 × 10-9esu. The dipole alignment exhibits a thermal stability even at 6°C higher than Tg and there is no significant SHG decay below 100°C due to the partial main-chain character of the polymer structure, which is acceptable for nonlinear optical device applications.

Novel Y-type polyester 4 containing 5-methyl-4-{5-(1,2,2-tricyanovinyl)-2- thiazolylazo}resorcinoxy groups as nonlinear optical (NLO) chromophores, which are parts of the polymer backbone, was prepared, and its NLO properties were investigated. Polyester 4 is soluble in common organic solvents such as N,N-dimethylformamide and dimethylsulfoxide. Polymer 4 shows a thermal stability up to 250 °C from thermogravimetric analysis with glass-transition temperature obtained from differential scanning calorimetry of approximately 94 °C. The second harmonic generation (SHG) coefficient (d33) of poled polymer film at 1560-nm fundamental wavelength is 8.12 × 10 -9 esu. The dipole alignment exhibits a thermal stability even at 6 °C higher than glass-transition temperature (Tg), and no significant SHG decay is observed below 100 °C due to the partial main-chain character of polymer structure, which is acceptable for NLO device applications.
