The last 20 years have evidenced an enormous increase of activity on introducing first row transition metal complexes of corroles as sustainable catalysts for clean production of energy from renewable resources. While triarylcorroles were used almost exclusively for those purposes, contemporary research exposed the demand for corroles that are much smaller in size. We now report the progress in that direction, which resulted in corrole metal complexes of the size required for strong absorbance onto electrodes used for fuel cells and other energy-relevant redox reactions.¹ This aspect is shown to come into play in the most important variables for efficient electrocatalytic hydrogen gas production from water: earlier onset potential, larger yield and longer durability.
