Fluorescence Spectroscopic Study on 2-(2-Pyridyl)imidazole at Different pH Values

Abstract

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
