Porphyrins and metalloporphyrins (or porphyrin coordination complexes) have been wildly investigated as photocatalysts in recent years. Herein we synthesized two new A3B porphyrins, a new asymmetric A3B zinc-porphyrin ligand with peripheral chelate group (pyridine dicarboxylate), and a ruthenium(II) complex of the porphyrin ligand. Their photo-physical properties were characterized and investigated by UV-Vis and fluorescent emission. The modeling of the molecular structures was optimized by DFT theoretical calculation. All porphyrin compounds exhibited strong absorbance at the Soret bands and Q bands. The free base of porphyrin possessed a higher quantum yield and a longer life time than the other two zinc-porphyrins and ruthenium-porphyrin in terms of fluorescence. Furthermore, the ruthenium-porphyrin complex can be used as a promising photocatalyst under visible light for two kinds of organic reactions: ketone-related oxidative aminothiocyanation (above 90% yield) and indole-related oxidative thiocyanation (around 80% yield) with a remarkable low amount (0.1 mmol %).

Paragraph 0066-0069, (2020/06/16)
The invention discloses an application of copper chloride dihydrate in photocatalysis of reaction of an indole compound and a thiocyanate compound. Specifically, under the atmosphere of oxygen or air,an indole compound, an ammonium thiocyanate compound and copper chloride dihydrate are added into a reaction container provided with a stirring device, ethyl alcohol is added, a stirring reaction isconducted for 20-30 hours under room-temperature illumination, and the 3-thiocyanate indole compound is obtained. According to the method, CuCl2.2H2O is directly used as a catalyst for the first timeunder the condition of not adding any photosensitizer. Besides, the efficient preparation of the 3-thiocyanate indole compound is realized, the whole process is green, efficient and easy to operate, and the application is a good method for synthesizing the 3-thiocyanate indole compound.
