合成及表征了一系列以柔韧碳氢链相连不同长度的ｐ／ｐ型单核铁（Ⅲ）双卟啉配合物，以可见光谱首次观察到该系列配合物在氯仿溶液中开放式及闭合式构象的平衡，发现６８０ｎｍ处吸收峰强度与这种构象平衡有关，烷氧链越长，该吸收峰强度越大．利用该类配合物模拟了细胞色素Ｐ４５０单加氧酶对环己烷的羟化作用，催化结果表明，在以分子氧为氧源及还原剂存在的温和条件下，该类配合物的催化活性显著高于单核铁卟啉（ＦｅＴＰＰＣｌ），随着柔韧碳氢链长度的增加，双卟啉的催化活性依次增加．高的催化活性与双卟啉配合物在溶液中的构象平衡，即闭合式构象引起的立体位阻及电子转移有关．
A series of p / p mononuclear iron (Ⅲ) porphyrin complexes with different length and length were synthesized and characterized. For the first time, the complexes of this series of complexes were found to be open and closed in a chloroform solution Conformational equilibrium and found 680nm absorption peak intensity with this conformational balance, the longer the alkoxy chain, the greater the absorption peak intensity. The use of these complexes to simulate the hydroxylation of cyclohexane by cytochrome P450 monooxygenase catalyzed results show that the catalytic activity of the complexes in the presence of molecular oxygen as a source of oxygen and a reducing agent Was significantly higher than that of mononuclear iron porphyrin (FeTPPCl). With the increase of the length of the flexible carbon chain, the catalytic activity of bisporphyrin increased in turn. The high catalytic activity is related to the conformational equilibrium of the bi-porphyrin complex in solution, namely steric hindrance and electron transfer due to the closed conformation.
