Two p-nitrylphenylamine Schiff bases synthesized by the reactions of four intermediate compounds and p-nitrylphenylamine were studied
and the compounds were characterized by Nuclear magnetic resonance
mass spectrum
ultraviolet spectroscopy and Fluorescence spectrometry.The results indicate that the intramolecular hydrogen bonds of Schiff base Ⅰ can enhance coplanarity
which is a key factor for effectively improving the Absorption cross-section of two-photon Absorption(TPA) compounds.
