A novel T-type polyurethane 7 containing 1-(2,5-dioxyphenyl)-2-{5-(1,2,2- tricyanovinyl)-2-thienyl}ethene groups as nonlinear optical (NLO) chromophores was prepared and characterized. Polyurethane 7 is soluble in common organic solvents such as DMF and DMSO. Polymer 7 shows a thermal stability up to 270°C from TGA thermogram and the Tg value obtained from DSC thermogram is around 155°C. The second harmonic generation (SHG) coefficient (d 33) of poled polymer film at 1560nm fundamental wavelength is 3.56 × 10-9esu. The dipole alignment exhibits a thermal stability even at 5°C higher than Tg, and there is no SHG decay below 160°C due to the partial main-chain character of the polymer structure, which is acceptable for nonlinear optical device applications.
