Post-Functionalization of Co(III)PPh3triarylcorroles through Suzuki-Miyarura Couplings and Their Tunable Electrochemically Catalyzed Hydrogen Evolutions and Oxygen Reductions

Abstract

he post-functionalization of six novel symmetric and asymmetric meso-expanded Co(III)corroles through Suzuki-Miyarura coupling reaction have succeeded along with their structural characterization. An analysis of the structure-property relationships in the optical and redox properties has been carried out by comparing their optical spectroscopy and electrochemistry. The results demonstrate that post-functionalized meso-expanded Co(III)triarylcorroles exhibited enhanced electrocatalyzed oxygen reduction reactions (ORRs) and that their reactivity can be modulated by modulating the electronic structure by changing the number as well as the functionalization of coupled meso-substituent.
