Solid State Synthesis, Characterization And Properties Of Oxygenated Tetraphenylporphyrin Fe(Ⅱ),Co(Ⅱ)

A study of metallporphyrin which can absorb O2 is an important aspect in the field of coordination chemistry and physical chemistry, because these compounds have the same properties of biologic oxygen carrier. Porphyrin ligands and their complexes have a broad application in the field of analytical chemistry, stereochemistry, electrochemistry, spectroscopy, biochemistry, catalysis, material, nuclear chemistry and other subjects.Solid-state chemistry shows its advantages in coordination chemistry greatly. In this paper we synthesize metallporphyrin complexes as oxygen carrier by solid-state reaction and study the oxygenation properties and comparison with those obtained from traditional liquid-state reaction. The contents of this work contain five parts:1. Prospect and application for Porphyrin complex were discussed. Recent development of oxygenation of cobalt complexes was reviewed, such as the structure and properties of some typical oxygen carriers.2. 5,10,15,20-meso-tetra-(P-phenyl) porphyrin were synthesized by benzaldehyde and pyrrole. Two new complexes were synthesized by solid-state reaction at room temperature. It was found that one mole of the complexes reacted with one mole of oxygen at room temperature. And the two oxygenated complexes were obtained and characterized by elemental analysis, IR spectra, 1HNMR, TG/DTA, MS, UV-vis, Karl Fischer method and molar conductance. The coordinated oxygen contents in the oxygenated complexes were also determined by weight method. The deoxygenated complexes were observed to absorb oxygen over again, which showed the complexes are able to bind molecular oxygen reversibly. 3. 5,10,15,20-meso-tetra-(P-hydroxyphenyl) porphyrin were synthesized by p-hydroxy benzaldehyde and pyrrole. They were synthesized by solid-state reaction at room temperature. It was found that one mole of complexes reacted with one mole of oxygen at room temperature. 5,10,15,20-meso-tetra- (P-methoxyphenyl) porphyrin were synthesized by p-methoxy benzaldehyde and pyrrole. They were synthesized by solid-state reaction at room temperature. It was found that one mole of complexes reacted with one mole of oxygen at room temperature. And the four oxygenated complexes were obtained and characterized by elemental analysis, IR spectra, 1HNMR, TG/DTA, XRD, UV-vis and molar conductance. The coordinated oxygen contents in the oxygenated complexes were also determined by weight method.4. 5,10,15,20-meso-tetra-(P-nitrophenyl) porphyrin were synthesized by p-nitro benzaldehyde and pyrrole. 5,10,15,20-meso-tetra-(p-amidophenyl) pophyrin were synthesized by 5,10,15,20-meso-tetra-(p-nitrophenyl) pophyrin. They were synthesized by solid-state reaction at room temperature. And the four oxygenated complexes were characterized by elemental analysis, IR spectra, 1HNMR, TG/DTA, UV-vis, Karl Fischer method and molar conductance. The coordinated oxygen contents in the oxygenated complexes were also determined by weight method.5. Summary for the contents of this paper was discussed. Prospect for oxygen carrier and the development of our work were reviewed.
