Abstract

Spectroscopic studies of the fluorescence emission of selected 1,3,4-thiadiazoles in organic solvents and an aqueous solution were carried out. An interesting effect of pH-induced dual fluorescence was observed in the aqueous solution. The use of organic solvents resulted either in a single fluorescence maximum, double fluorescence (two well-resolved emission bands), or the dual fluorescence effect. The results obtained suggest that the fluorescence emission effects in 1,3,4-thiadiazoles are associated with both the conformational isomerism and the chromophore aggregation phenomena.
