摘要/Abstract

摘要： 合成了2-(2-吡啶基)咪唑,并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2-(2-吡啶基)咪唑化合物存在分子内光诱导电子转移反应(PET),并且这一过程强烈地依赖于溶液的pH值,但是氮原子的质子化会影响PET过程.

Abstract: 2-(2-Pyridyl)imidazole(2PI) 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.

Key words: 2-(2-Pyridyl)imidazole, Fluorescence spectrum, Intramolecular photoinduced electrontransfer, pH effect
