Two
peripheral functionalized clamp-shaped cobalt porphyrin(2.1.2.1)
complexes were synthesized, and their electrocatalytic ORR abilities
were investigated. The crystal data and optical and redox properties
of them were revised by peripheral modification. The ORR capacities
and DFT calculations of F5PhCo and F5NCo suggest superior selectivity for the 4e– ORR pathway.
This work further confirms the clamp-shaped cobalt porphyrin complexes
are ideal Co–N4 ORR catalysts.
