Phosphorus Corroles: Tuning of their Photophysical and Redox Properties via Axial Ligation and Macrocycle Modification

Abstract

Given the increased interest in phosphorus corroles for many applications, we now report how their photophysical variables and redox potentials may be tuned. This was performed by focusing on a series of derivatives that significantly differ in terms of the chelating corrole macrocycle: three C6F5 vs. three CF3 substituents on the meso‐C atoms, H vs. Br atoms on the β‐pyrrole positions, and monomeric vs. dimeric (through β‐pyrrole C−C bonds). Also studied was the effect of the phosphorus axial ligands, hydroxide vs. fluoride.
