抄録

The authors describe herein the polymer-bound cobalt porphyrin derivatives with large oxygen-binding kinetic constants and with extraordinarily prolonged lifetimes through which oxygen permeates with high selectivity. They have recently reported measurements of facilitated oxygen transport in dry (or solvent-free) polymer membranes containing a cobalt porphyrin and a cobalt-Schiff base chelate as a fixed carrier which sorbs oxygen selectively and reversibly. They intended here to enhance the efficiency of this facilitated transport and to prolong the lifetime of the metal chelate as an oxygen carrier. It is described in this paper the effects of polymer-bound CoP structure on the lifetime of oxygen-binding ability, the oxygen-binding kinetic constants, and the facilitated oxygen transport in the membrane and discuss the oxygen-transport mechanism by a dual-mode transport model.
