Positional Isomerism

In this study, four meso-expanded Co(III)corroles at meta-positions through Suzuki–Miyaura coupling reactions and their structural characterization are successfully accomplished and reported. An analysis of the structure–property relationships by spectroscopy, electrochemistry and electrochemical catalysis demonstrate how the positional isomerism influence the electronic structure and their catalytic behaviors of hydrogen evolution reactions (HERs) and oxygen reduction reactions (ORRs).
