Porphyrin‐Based Organophotocatalysts

Abstract

The planar geometric structure and the rich absorption feature endow porphyrins with interesting optoelectronic properties and also make it promising building blocks for supramolecular assembly. Recent advances in the photocatalytic applications of porphyrins, including homogeneous, heterogeneous photocatalysis, and photoelectrochemical solar cells are highlighted. Porphyrin photocatalysts are involved in the form of molecules, supported molecules, nanostructures, and thin film. Related rational design strategies are provided for each form with an aim to enhance the light conversion efficiency. Finally, the ongoing directions and challenges for the future development of porphyrin semiconductors in high-quality optoelectronic devices are also proposed.

“…Photocatalysis is increasingly being emphasized as an environmentally friendly process for decomposing organic pollutants in polluted water and air. It is well-documented that porphyrins and metalloporphyrins contribute significantly to photooxidation catalysis [26]. Despite the feasibility, homogeneous porphyrin photocatalysts have not been practically commercialized.…”
