The pore surface of a porous glass membrane was modified with phthalocyanato- and tetraphenylporphyrinato-1-(benzylimidazole)cobalt(II) complexes, which specifically and reversibly binds molecular oxygen from air. The lower oxygen-binding affinity enhanced surface oxygen diffusion which improved permeability (3:0 × 10 -11 kmol m s -1 m -2 kPa -1) and (oxygen/nitrogen) permselectivity (10).
