N2 - A meso-tetrakis(α,α,α,α-o-pivalamidophenyl)porphyrinatocobalt(II) derivative bearing covalently-bound imidazole (Scheme 1, CoPim) was synthesized. Oxygen-binding to CoPim was rapid and reversible. The CoPim in the solid state chemically adsorbed oxygen (20 ml O2/g CoPim), which was ca. 40-times greater than the physical adsorption amount. The oxygen-binding lifetime of CoPim was longer than that for the corresponding porphyrinatocobalt (II) with an externally added imidazole. The efficiency of CoPim as an oxygen carrier was demonstrated by oxygen-enrichment from air using a pressure-swing adsorption experiment.
