Chemically Specific Surface Diffusion of Oxygen through a Porous Membrane Modified with Cobalt Porphyrin on Its Pore Surface

Chemically specific surface diffusion of oxygen was observed on a porous glass membrane modified on its pore surface with cobalt porphyrin (CoP) which binds oxygen specifically and reversibly from air.The membrane displayed both permselectivity for oxygen

Controlling Oxygen Reduction Selectivity through Steric Effects: Electrocatalytic Two-Electron and Four-Electron Oxygen Reduction with Cobalt Porphyrin Atropisomers

Achieving a selective 2 e? or 4 e? oxygen reduction reaction (ORR) is critical but challenging. Herein, we report controlling ORR selectivity of Co porphyrins by tuning only steric effects. We designed Co porphyrin 1 with meso-phenyls each bearing a bulky ortho-amido group. Due to the resulted steric hinderance, 1 has four atropisomers with similar electronic structures but dissimilar steric effects. Isomers αβαβ and αααα catalyze ORR with n=2.10 and 3.75 (n is the electron number transferred per O2), respectively, but ααββ and αααβ show poor selectivity with n=2.89–3.10. Isomer αβαβ catalyzes 2 e? ORR by preventing a bimolecular O2 activation path, while αααα improves 4 e? ORR selectivity by improving O2 binding at its pocket, a feature confirmed by spectroscopy methods, including O K-edge near-edge X-ray absorption fine structure. This work represents an unparalleled example to improve 2 e? and 4 e? ORR by tuning only steric effects without changing molecular and electronic structures.

Complexation of sterically hindered cobalt porphyrin with 1-methylimidazole along the axial coordinate and the reaction of reversible binding of oxygen

The complexation of a sterically hindered cobalt porphyrin with 1-methyl imidazole and its reaction of reversible binding of oxygen was studied. Spectrophotometry and potentiometry were used to determine the equilibrium constant of the oxygenation process.
