Abstract
A novel T-type polyester (7) containing 1-(2,5-dioxyphenyl)-2-{5-(1,2,2-tricyanovinyl)-2-thienyl}ethene 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 T g value obtained from DSC near 113°C. The second harmonic generation (SHG) coefficient (d 33 ) of poled polymer film at the 1560 nm fundamental wavelength was around 4.42 × 10−9 esu. The dipole alignment exhibited a greater thermal stability even at 10°C higher than T g , and there was no SHG decay below 125°C due to the partial main-chain character of the polymer structure, which is acceptable for nonlinear optical device applications.
