5-(4-phenoxyacetic acid)-10,15,20-triphenyl zinc porphyrin and preparation method thereof

The invention provides a novel water-insoluble porphyrin, namely 5-(4-phenoxyacetic acid)-10,15,20-triphenyl zinc porphyrin. The water-insoluble porphyrin is obtained by adopting 5-(4-hydroxyphenyl)-10,15,20-triphenyl zinc porphyrin as a raw material through coordination with zinc acetate, ethyl chloroacetate substitution reaction and acid neutralization reaction. Because the hydroxyl in the 5-(4-phenoxyacetic acid)-10,15,20-triphenyl zinc porphyrin is converted into soluble carboxyl, the 5-(4-phenoxyacetic acid)-10,15,20-triphenyl zinc porphyrin can be dissolved into water to a certain extent and particularly has favorable dissolubility under the alkaline condition. Compared with the hydroxyl, the carboxyl is better qualified for a task of electronic transmission, and the invention provides a good platform for further researching a photoelectronic functional material.
