Synthesis and stability studies of conformationally locked 4-(diarylamino)aryl- and 4-(dialkylamino)phenyl-substituted second-order nonlinear optical polyene chromophores
A genericapproach to high temperature stable, functionalizedpolyimides for nonlinearoptics has been developed and the resulting polyimides exhibit excellent temporal stability in dipole orientation at elevated temperatures, such as 150degrees}C. Large second harmonic generation coefficients and electro-optic coefficients have been achieved. These polyimides exhibit good solubility in common organic
