Summary: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 (...) obtained from differential scanning calorimetry thermogram of around 94...C. The second harmonic generation (SHG) coefficient (...) of poled polymer film at 1064 nm fundamental wavelength is 8.12 x 10... esu. The dipole alignment exhibits a thermal stability even at 6...C higher than ... 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.
