Abstract
The current work describes the comparative study of the photophysical properties of new series of xanthylium fluorophore in different organic solvents, the effect of pH, and the effects of UV light irradiation and stability. The designed molecule plays a significant role in the stability. We disclosed the synthesized molecule's stability from UV–Vis, fluorescence, theoretical studies, the molecule sensitivity to solvent polarity, and pH due to its structural nature. The decrease in absorbance and fluorescence intensity with UV–visible light irradiation for the solid and liquid samples were studied. The dye discoloration rate was estimated. The mechanism for the same has been explored, and the information is given in detail. The electrostatic potential, surface mapping analysis, and the stability of the synthesized dye molecules were studied theoretically and compared with the experimental outcome. The stability study and other factors allowed us to predict the suitable application of the synthesized xanthylium fluorophore.
