Zn1-xTixO NPs were efficiently synthesized using a simple solution free mechanochemical method. The synthesized ZnO and Ti(IV)-doped ZnO catalysts are exhibited polycrystallinity, a hexagonal crystal structure, and roughly spherical agglomerates. The surface areas of the Zn1-xTixO catalysts were positively correlated with the doping percentage of Ti(IV), which also enhanced the Lewis acidity of the NPs. The catalysts exhibited excellent activity during the synthesis of fluorescein dyes. This methodology was also extended to sulfone-fluorescein dye synthesis.

Fluorescein has several applications owing to its properties, such as high molar absorptivity, high fluorescence quantum yield, high photostability, and wavelengths of absorption and emission in the visible region. The syntheses of fluorescein derivatives between phenol and anhydride derivatives by using NbCl5 as a Lewis acid is described. The products have high yields and short reaction times are observed. The study of the UV/Vis and fluorescence spectra of these derivatives and their application in dye-sensitized solar cells is also described.
