摘 要:合成了N-(β-萘甲基)-N,N-二(2-哌嗪乙基)胺,并对其进行了表征,通过稳态荧光光谱研究了它在溶液中的光物理行为及溶液酸碱度的影响,发现N-(β-萘甲基)-N,N-二(2-哌嗪乙基)胺化合物存在分子内光诱导电子转移PET(Photoinduced Electron Transfer)过程,并且这-过程强烈的依赖于溶液的pH.N- (naphthalen-2-ylmethyl-N, N-Bis ( 2- (piperazin- 1-y1 ) ethyl ) amine was synthesized and the photophysical behavior in aqueous solution was studied in a wide range of acidity by steady- state fluorescence spectroscopy measurement. It was found that the intramolecular photoinduced electron transfer (PET)took place in the solution and the process strongly depended on the acidity of the solution and was affected by the protonation of nitrogen atoms.
