Porphyrin-based nanoporous materials for photocatalytic applications.

This article focuses on the design, properties, and photocatalytic applications of porphyrin-based nanoporous materials, emphasizing their potential in artificial light harvesting for solar energy conversion. Porphyrin derivatives, macrocyclic organic compounds with unique photophysical and redox properties, serve as versatile building blocks for various porous frameworks including metal-organic frameworks (MOFs), covalent organic frameworks (COFs), hydrogen-bonded organic frameworks (HOFs), and amorphous porous organic polymers (APOPs). These materials combine the light absorption and catalytic capabilities of porphyrins with high surface area and porosity, enabling applications such as photocatalytic CO2 reduction and water splitting. Despite challenges like photobleaching, synthetic complexity, and scalability, ongoing research highlights their promise for sustainable energy technologies and encourages interdisciplinary efforts to advance their practical use.
