| Abstract |
This paper describes the synthesis and optical sensing properties of fluorescence dye for proton and water. Dye was prepared by the attachment of a guanidine moiety to anthracene and applied as fluorescent pH sensors and water sensors. The fluorescence intensities of dye decreased with increasing pH values in the pH range between 11 and 13. The sensing mechanism was explained by the photoinduced electron transfer process. Dye was also useful as optical sensors for detecting the trace amount of water content in water-miscible organic solvents such as EtOH, CH3CN, DMF, THF and 1,4-dioxane. The fluorescence intensities of dye increased with increasing water content in organic solvents. The nitrogen atom of the dye was protonated in the presence of water in organic solvents and the PET was inhibited to restore fluorescence emission.
