Abstract

The invention provides a zinc protoporphyrin containing a heterocyclic ring as well as the synthesis and the applications of the zinc protoporphyrin containing a heterocyclic ring and a metal complex of the zinc protoporphyrin containing a heterocyclic ring, belonging to the technical field of solar cell applications. In the zinc protoporphyrin containing a heterocyclic ring, benzaldehyde, a derivant of benzaldehyde and pyrrole serve as raw materials, multiple steps of reactions, such as condensation, coordination, substitution and the like are carried out, and a zinc protoporphyrin monomer molecule containing a heterocyclic ring substituted group and a metal complex of the zinc protoporphyrin monomer molecule containing a heterocyclic ring substituted group are successfully synthesized. The photoelectric property research on the zinc protoporphyrin containing a heterocyclic ring and the metal complex of the zinc protoporphyrin containing a heterocyclic ring in preparing the sensitization crystal TiO2 solar cell shows that the zinc protoporphyrin containing a heterocyclic ring and the metal complex of the zinc protoporphyrin containing a heterocyclic ring have good application prospects in the sensitization solar cell.

Description

technical field [0001] The invention belongs to the technical field of chemical application, and relates to the synthesis of a heterocyclic zinc porphyrin and its metal complex; the invention also relates to the zinc porphyrin and its metal complex as a sensitizer in the preparation of dye-sensitized solar energy Applications in battery electrodes. Background technique [0002] In recent years, the design and synthesis of optoelectronic functional materials and devices using the unique electronic structure and optoelectronic properties of porphyrin and its complexes has become a very active research field in the world. Porphyrin compounds have their unique advantages as sensitizers: porphyrin is very stable and has an adjustable redox potential, and has strong absorption in the visible light region, which can promote the sensitization of semiconductor materials (TiO 2 ) are responded in the visible light range; easy to design and chemically modify, and low cost. In recent ...
