The design, synthesis, and nonlinear optical properties of novel X-type polyurethane containing dicyanovinylnitroresorcinoxy group with enhanced SHG thermal stability

Novel X-type polyurethane 5 containing 4-(2′,2′-dicyanovinyl)- 6-nitroresorcinoxy groups as nonlinear optical (NLO) chromophores, which constitute parts of the polymer backbone, was prepared and characterized. Polyurethane 5 is soluble in common organic solvents such as acetone and N,N-dimethylformamide. It shows thermal stability up to 280 C from thermogravimetric analysis with a glass transition temperature (Tg) obtained from differential scanning calorimetry thermogram of around 120 C. The second harmonic generation (SHG) coefficient (d33) of poled polymer film at 1064-nm fundamental wavelength is around 6.12 × 10-9 esu. The dipole alignment exhibits a thermal stability even at 5 C higher than Tg, and there was no SHG decay below 125 C due to the partial main chain character of the polymer structure, which is acceptable for NLO device applications.

Synthesis and nonlinear optical properties of novel polyurethane containing cyanovinylnitroresorcinoxy group

Novel X-type polyurethane 5 containing 4-(2′-carbomethoxy-2′-cyano)vinyl-6-nitroresorcinoxy groups as nonlinear optical (NLO) chromophores, which constitute part of the polymer backbone, was prepared and characterized. Polyurethane 5 is soluble in common organic solvents such as acetone and N,N-dimethylformamide. It shows thermal stabilities up to 260°C from thermogravimetric analysis with glass transition temperature obtained from differential scanning calorimetry near 108°C. The second harmonic generation (SHG) coefficient (d33) of poled polymer film at 1064 nm fundamental wavelength is 9.83 × 10-9 esu. Polymer 5 exhibits a high thermal stability even at 2°C higher than Tg, and no significant SHG decay is observed below 110°C, which is acceptable for nonlinear optical device applications.

Synthesis and nonlinear optical properties of novel polyester containing tricyanovinylthiophene with enhanced thermal stability of second harmonic generation

A novel Y-type polyester (7) containing 1-(2,4-dioxyethoxy)phenyl-2-{5-(1, 2,2- tricyanovinyl)-2-thiophenyl)}ethenyl groups as NLO-chromophores was synthesized and characterized. Polymer 7 was soluble in common organic solvents such as DMF and DMSO. It showed thermal stability up to 300°C in TGA with Tg value obtained from DSC near 134°C. The second harmonic generation (SHG) coefficient (d33) of poled polymer film at the 1,560nm fundamental wavelength was around 6.74×10-9 esu. The dipole alignment exhibited high thermal stability and there was no SHG decay below Tg due to the partial main-chain character of polymer structure, which was acceptable for NLO device applications.

A novel Y-type polyurethane 7 containing 1-(2,4-dioxyethoxy)phenyl-2-{5-(1, 2,2- tricyanovinyl)-2-thiophenyl)}ethenyl groups as nonlinear optical (NLO)- chromophores, which are components of the polymer backbones, was prepared. Polyurethane 7 is soluble in common organic solvents such as DMF and DMSO. It showed a thermal stability up to 280°C in TGA thermogram and the T g value obtained from DSC thermogram was around 163°C. The second harmonic generation (SHG) coefficient (d33) of poled polymer film at 1560nm fundamental wavelength was around 3.72×10-9 esu. The dipole alignment exhibited a thermal stability up to near Tg, and there was no SHG decay below 150°C due to the partial main-chain character of the polymer structure, which is acceptable for nonlinear optical device applications.

Preparation of novel Y-type nonlinear optical polyimides with high thermal stability of second harmonic generation

2,4-Bis-(3,4-dicarboxyphenylcarboxyethoxy)-1-(2,2-dicyanovinyl)benzene dianhydride (4) was prepared and reacted with 1,4-phenylenediamine and 4,4'-oxydianiline to yield novel Y-type polyimides 5-6 containing 2,4-dioxybenzylidenemalononitrile groups as NLO-chromophores, which constitute parts of the polymer backbone. The resulting polyimides 5-6 are soluble in polar solvents such as dimethylsulfoxide and N,N-dimethylformamide. Polymers 5-6 showed a thermal stability up to 330°C in thermogravimetric analysis thermograms with Tg values obtained from differential scanning calorimetry thermograms in the range 179-188°C. The second harmonic generation (SHG) coefficients (d33) of poled polymer films at the 1064 nm fundamental wavelength were around 6.32 × 10-9esu. The dipole alignment exhibited exceptionally high thermal stability even at 20°C higher than Tg, there was no SHG decay below 200°C because of the partial main chain character of polymer structure, which is acceptable for nonlinear optical device applications.
