Ultra-thin polymer films containing metal/metal complex, cobalt(II) meso-tetraphenylporphyrin(CoTPP), have been prepared by vacuum codeposition of metal/metal complex and organic monomer or macromolecular prepolymer onto the substrate and oxygen binding to the metal center of CoTPP has been studied. CoTPP is capable of binding oxygen reversibly and in a special circumstance binding oxygen irreversibly, which strongly depends on the dispersed metal phase state in the solid films. An oxygen molecule can be bound to the one metal center of CoTPP reversibly and shared with two metal centers of adjacent CoTPP molecules irreversibly. The results of oxygen uptake measurements has showed that 75% of metal complex molecules are capable of binding oxgen reversibly. |
