Abstract

The copolymer of [α,α′,α″,α$PPRM″-meso-tetrakis (o-methacrylamidophenyl)porphinato]cobalt with hexyl methacrylate (1) gives a transparent and flexible membrane. The covalently introduced (porphinato)cobalt reversibly forms its oxygen adduct in the membrane state. Oxygen-permeation behavior through the membrane is in accordance with a dual-mode transport model. Ratio of Dc to DD and DD are diffusion coefficients of oxygen via the fixed (porphinato)cobalt and through polymer matrix) is 10 times larger for the copolymer membrane 1 in comparison with that for the dispersed membrane 2, which indicates effective facilitation in the oxygen transport.
