With the breakthrough of Corrole synthesis, a variety of transition metal Corroles with unique electronic structure and their catalysis in various chemical processes have gradually attracted people’s attention. However, the study on the non-transition metal Corrole was relatively less. Gross synthesized aluminum, gallium Corroles and found that they have interesting photophysical properties and could be easily to turn into water-soluble derivatives for the study on the spectral properties of non-transition metal compounds. These unique properties make gallium Corrole a good prospect in molecular devices, photodynamic therapy, medicine, dye-sensitized solar cells and fluorescent probe. Therefore, this thesis focus on the synthesis and the study on Photophysical Properties of gallium corroles. This paper synthesized a series of gallium Corrole with different electronic structure, and investigated the nature of their absorption and emission spectra and the effects of the different solvents. This paper also prepared and identified gallium Corrole complexes with no axial coordination. The main contents of this thesis are as follows:1. Several corrole derivatives 5,10,15-tris(phenyl)corrole(1), 5,15-bis(phenyl)-10- (pentafluorophenyl)corrole(2), 5,15-bis(pentafluorophenyl)-10-(phenyl)corrole(3), 5,10,15- tris(pentafluorophenyl)corrole(4) and their gallium complexes (1-Ga(Py), 2-Ga(Py), 3-Ga(Py), 4-Ga(Py)) have been synthesized. The new synthesized 1-Ga(Py), 2-Ga(Py), 3-Ga(Py), 4-Ga(Py) were characterized by ES1-MS, UV-Vis and 1H NMR spectrum.2. Studied the effects of different solvents on the UV-visible spectra and steady state fluorescence spectra of gallium complexes (1-Ga(Py), 2-Ga(Py), 3-Ga(Py), 4-Ga(Py)). Also investigated changes in the UV-visible spectra and steady state fluorescence spectra of gallium complexes at different pH values. Discussed preliminarily the regularity between the changes of spectra and solvent properties (refractive index n, dielectric constantε).3. Prepared no axial ligand gallium Corrole complexes and confirmed its structure by 1H NMR. The interaction between different ligands and non axial ligand gallium Corrole complexes and itsπ-πstacking effects were also investigated.
