, p. 196 - 203 (2009)
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.

Synthesis of novel Y-type nonlinear optical polyurethane containing tricyanovinylthiophene with high thermal stability of dipole alignment

, p. 204 - 211 (2009)
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.
