摘要
合成并表征了4个中间体及由其与对硝基苯胺作用得到的2种对硝基苯胺Schiff碱,并通过核磁共振谱、质谱、紫外光谱及荧光光谱等测试手段对化合物进行了表征.结果表明,Schiff碱Ⅰ分子内的氢键可以增加分子的共平面性,是有机双光子吸收材料化合物吸收截面得到有效提高的关键因素.
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.
