The steadystate spectroscopy and the femtosceond fluorescence upconversion in three kinds of Ga Corroles in toluene and ethanol solvent have been studied. The results show that the effect of the hydroxyl and PTZ substitution on the properties of those Corroles is not significant. In contrast

of those Corroles varied significantly in different solvents. Evidently

solvent has a significant effect on those Corroles-energy level structure and optical properties.
