摘要：

The relationship of the fluorescence spectral characteristics of the anionic form of the molecular probe 4'-(diethylamino)-3-hydroxyflavone (FET) to intramolecular proton transfer in a weakly polar solvent (CH2Cl2) was studied. The fluorescence spectrum of this form had a broad featureless band in the area between the shortwavelength and long-wavelength fluorescence bands of FET. Its excitation spectrum had strong UV maxima (350 and 305 nm). This fluorescence disappeared completely if the solution was cooled to 1 A degrees C. The deprotonation mechanism of neutral FET molecules was discussed.
