Chromium(III) complexes of 2,3,7,8,12,13,17,18-octakis(propyl)porphyrazine and 2,3,9,10,16,17,23,24-octa substituted phthalocyanine were synthesized, characterized and the kinetics of metalation and redox activity studied and reported. The results obtained indicated that the rate of incorporation of Cr(III) into the central cavity of the ligands is a function of the kinetic inertness and size of the metal ion as well as the peripheral substituents of the ligand. The Cr(III) complex of 2,3,7,8,12,13,17,18-octakis(propyl)porphyrazine exhibited a metal based reduction. Hence it was concluded that the nature of the incorporated metal ions has an influence on the rate and mechanism of incorporation of the metal ion and also the redox activities of these complexes.
对 2,3,7,8,12,13,17,18-octakis(propyl)porphyrazine 和 2,3,9,10,16,17,23,24-octa 取代的酞菁的铬(III)配合物进行了合成、表征,并研究和报告了金属化动力学和氧化还原活性。研究结果表明,铬(III)掺入配体中心空腔的速率是金属离子的动力学惰性和大小以及配体外围取代基的函数。2,3,7,8,12,13,17,18-八(丙)卟嗪的 Cr(III) 复合物表现出基于金属的还原。因此可以得出结论,掺入的金属离子的性质对金属离子的掺入速率和机理以及这些配合物的氧化还原活性都有影响。
