The oxygen carrier capable of reversible adsorption of the molecular oxygen is a class of transition metal complexes. Dioxygen complexes of transition metals and its effect on the activation of molecular oxygen is very active in the disciplines of inorganic, biological, and catalytic subject. Its research may uncover a variety of in vivo oxygen carrier at the molecular level, the mechanism of action of the oxidase, peroxidase, and superoxide dismutase, paved road. The reversible complexation of transition metal complexes with molecular oxygen and activation of molecular oxygen as an important way to explore the mechanism of hemoglobin biological enzyme. Meanwhile, many fine organic synthesis of the catalytic oxidation process is also associated with the degree of activation of the molecular oxygen. Cobalt Schiff base complexes with the performance of the oxygen carrier is an important aspect of the coordination chemistry, since such complexes having a similar to the nature of the biological oxygen carriers. Schiff base ligand containing multi-functional base, not only to obtain a stable transition metal complexes, and these ligands and their complexes in stabilizers, dyes and pigments, reaction of the ligand, structural chemistry, and agriculture plays an important role . Macrocyclic complexes of the dual-core protein activated in a simulated metal center, bonding with the activation of small molecules and has a broad application prospects as a bifunctional catalyst. The solid-phase chemistry is an important part of materials chemistry. In recent years, solid-phase reaction to show the great superiority of the chemical reaction of the ligand. In this paper, the solid-phase synthesis of Schiff base cobalt complexes as oxygen carriers, the nature of their oxygenation and compared. The paper is divided into six chapters. Review the recent development of the oxygen carriers, gave a brief description of some typical oxygen carriers, and described the progress of the macrocyclic complexes. Ethylenediamine Cobalt, with room-temperature solid-phase method synthesis anisaldehyde were characterized using IR, XRD, elemental analysis, and explore its oxygen-carrying performance. lt; WP = 3 gt; 3. anisaldehyde of ethylenediamine with different Co salt complexes oxygenation. 4. The preparation of the Schiff base ligands, at room temperature grinding method using solid phase synthesis of some of the Schiff bases cobalt complexes, and their oxygen-absorbing performance compared to obtain a number of new compounds. By solid-phase reaction of two new complexes of o-aminothiophenol cobalt and ethanolamine cobalt, and were characterized by elemental analysis, IR and other methods. Direct synthesis of macrocyclic 3,6,9,12,20,23,26,29 - eight aza -35,36 - dihydroxy -16,33 - dimethyl - tricyclo [29,3,1,114 18] hexadecane -1 (34), 14,16,18 (36), 31,32 - hexaene hydrobromide, potentiometric titration was determined protonation constant as well as copper, cobalt complexes The stability constants and study their formation conditions.
