Photoelectric performance of polyphosphazenes grafted functional group

Photoelectric properties of three nonlinear compounds which were phenol polyphosphazene grafted by paranitroaniline,phenol polyphosphazene grafted by 2,4-dinitroaniline and carbazole polyphosphazene grafted by 2,4-dinitroaniline respectively that different functional groups were grafted to the polyphosphazenes mian chain were measured.The photoelectric conductivity and the electrooptic coefficients of carbazole polyphosphazene grafted by 2,4-dinitroaniline was the best of them.Through exploration the relations between functional group structure and photoelectric performance of polyphosphazene to provide theoretical support for the experimental design for synthesis of new nonlinear materials.
