Abstract
A new Co 5,10,15,20-tetrakis(2′,6′-dipivaloyloxyphenyl)porphyrin () with eight ester groups in all ortho and ortho′ positions of phenyl groups was designed, which displayed significantly improved 2e oxygen reduction reaction (ORR) selectivity compared with a 5,10,15,20-tetrakis(para-dipivaloyloxyphenyl) porphyrin () without large steric groups. This work is significant to reveal the steric hindrance effect of metal porphyrins on electrocatalytic ORR selectivity.
