Abstract
The fluorescence properties of 1-naphthol, 2-naphthol and 1,2,3,4-tetrahydronaphthol were obtained in binary aqueous-alcohol solvents with and without beta-cyclodextrin. The fluorescence of both the molecular and anionic forms of 1-naphthol and 2-naphthol were observed in the binary solvents without beta-cyclodextrin. Only the fluorescence of the molecular form of 2-naphthol appeared in the binary solvents with beta-cyclodextrin present, and its fluorescence was quenched with increasing amounts of beta-cyclodextrin. However, the fluorescence intensity of the molecular form of 1-naphthol increased with an increasing amount of beta-cyclodextrin in the binary solvents. The fluorescence intensity of 1,2,3,4-tetrahydronaphthol decreased with an increase in the amount of beta-cyclodextrin. The fluorescence results were interpreted with the Stern-Volmer equation and a modified Stern-Volmer equation.
