Octa-.beta.-phosphonate-substituted porphyrins for efficient and scalable visible light photocatalysis

Porphyrins have been studied across various disciplines, including materials science, physics, biology, and medicine. Their growing popularity primarily results from the wide range of functions performed by naturally occurring tetrapyrrolic macrocycles. These compounds play crucial roles in photosynthesis, oxygen and electron transport, and various catalytic transformations. This functional versatility of porphyrinoids is possible due to subtle structural changes in the peripheral substituents and the complex biological environments in which they operate. One notable application of these compounds is photocatalysis, which has experienced significant growth in the past two decades, thanks to the development of photoredox-catalyzed reactions. Porphyrin photocatalysts already hold marked importance in oxidation reactions and photoredox-catalyzed C–C bond-forming reactions. The pivotal advantages of using porphyrins as red-light-excited photoredox catalysts were also recently demonstrated. However, their broader utilization in photocatalysis remains underdeveloped, primarily due to the challenges of their laborious synthesis and poor solubility in non-chlorinated solvents. This project aims to develop the next generation of porphyrin photocatalysts for reactions driven by visible light, with the goal of increasing the efficiency of photoreactions by reducing photocatalyst loading to ppm levels and preparing reusable photocatalysts.
