A thin membrane of the cobalt-tetraphenylporphyrin (CoTPP) complex with the copolymer of octyl methacrylate and vinylimidazole (OIm) was successfully prepared with the thickness of 80 ∼ 90 nm on a porous support membrane. The cobaltporphyrin-highly loaded membrane showed a high performance in the facilitated transport of oxygen. Homogeneous distribution of the CoTPP throughout the membrane and complexation with the imidazolyl residue of Olm with a 5-coordinated structure are described.
