Novel porphyrin ligand and metal complex, preparation method and application for novel porphyrin ligand

Abstract

The invention relates to a novel porphyrin ligand and a metal complex, a preparation method and application for the novel porphyrin ligand. The complex has potential application values in fields of dye sensitization solar cells, organic catalytic chemistry, material chemistry and the like. Firstly, 4-formoxyl methyl benzoate and pyrrole serve as raw materials to synthesize TCPP-Me, TCPP is obtained by hydrolyzing the TCPP-Me, one of a Tyr4-TCPP, a Tyr3-TCPP, a Tyr2-TCPP-1, a Tyr2-TCPP-2 and Tyr-TCPP is obtained by reacting the TCPP and tyrosine ethyl ester, and finally each ligand is reacted with corresponding metal salt to respectively obtain complexes corresponding to the ligand and the metal salt. A Tyr3-TCPP-Zn (II) shows a high open-circuit voltage in an application of a DSSC aspect.

Description

technical field [0001] The invention relates to a novel porphyrin ligand, its metal complex, its preparation method and application. Background technique [0002] Porphyrin is a general term for a class of macrocyclic compounds with substituents on the porphine ring, and has a special rigid π-electron delocalized structure. In the porphyrin macrocycle, the four nitrogen atoms constitute an environment with certain spatial positions and coordination capabilities, which can form stable complexes with metals. If the substituents are changed on the porphyrin ring, the electron-donating ability of the four nitrogen atoms is adjusted, different central metal ions are introduced, or axial ligands with different nucleophilicities are changed, the porphyrin and metalloporphyrin will have different properties, and therefore have different functions. Therefore, porphyrins and metalloporphyrins are widely used in the fields of solar cell materials, conductive materials, energy chemist...

AI Technical Summary

Problems solved by technology

The advantage of the Adler method is that it is easy to operate, the reaction conditions are not harsh, and more than 70 kinds of porphyrin compounds can be prepared, but it is difficult to form the corresponding porphyrins for acid and heat unstable aldehydes by this method.
