Fourier transform infrared spectroscopy measurement showed that the polymerization of N9FPA occurred mainly at the C（2） and C（7） positions. The fluo- rescence spectra indicated that PN9FPA films were blue-light emitters. In addition, the structures and properties of the monomer and the polymers were characterized and evaluated with CV, UV, TGA and SEM.展开更多
