Abstract

A membrane having both a selective oxygen-absorbing capability and a long operational lifetime was prepared by complexing picket-fence cobaltporphyrin (CoP) with poly(vinylimidazole-co-fluoropentyl methacrylate) (FIm) as a polymer-ligand. The oxygen-binding affinity of the CoP complexed in the membrane was larger than that in the solution state. Oxygen permeation was selectively facilitated with the CoP fixed in the membrane, and a high oxygen permeability (10^-7 cm³(STP) cm cm^-2 s^-1 cmHg^-1) maintaining the permselectivity was observed. The lifetime of the CoP as an oxygen-carrier was prolonged by complexing with Fire even in a humid atmosphere (half-lifetime > 200 days) due to the hydrophobic property of the FIm copolymer.
