Description
Summary:A new Y-type polyester (3) containing nitrophenylazoresorcinoxy groups as NLO chromophores, which are components of the polymer backbone was prepared. Polyester 3 is soluble in common organic solvents such as N,N-dimethylformamide and acetone. It shows a thermal stability up to 240...C from thermogravimetric analysis with glass-transition temperature (...) obtained from differential scanning calorimetry near 116...C. The second harmonic generation (SHG) coefficient (...) of poled polymer films at the 1064 nm fundamental wavelength is around 4.63 x 10... esu. The dipole alignment exhibits a thermal stability even at 4...C higher than ..., and no SHG decay was observed below 120...C due to the partial main-chain character of polymer structure, which is acceptable for NLO device applications.
