尾式金属卟啉配合物的研究（Ⅲ）──咪唑基尾式卟啉及其铁（Ⅲ）配合物的合成和性质

Studies on Tailed Metalloporphyrin Coordination Compounds(Ⅲ)──The Synthesis and Properties of an Imidazolyl Tailed Porphyrin and Its Iron(Ⅲ) Coordination Compound

合成了咪唑基尾式卟啉──５－邻［４－（１－咪唑基）丁氧基］苯基－１０，１５，２０－三苯基卟啉（ｏ－ＩｍＢＰＴＰＰ）及其铁（Ⅲ）配合物［Ｆｅ（Ⅲ）（ｏ－ＩｍＢＰＴＰＰ）Ｃｌ］，以元素分析、质谱、１ＨＮＭＲ、ＩＲ和紫外可见吸收光谱等进行了表征。初步研究了在氯仿和苯中某些含氮配体与铁（Ⅲ）配合物的轴向配位性质。结果表明，Ｆｅ（Ⅲ）（ｏ－ＩｍＢＰＴＰＰ）Ｃｌ通常与含氮配体生成低自旋的六配位加合物，但在苯溶液中与咪唑作用时，一定条件下还能生成稳定的高自旋五配位加合物。

A imidazolyl tailed porphyrin,5-[o-(1-imidazolyl) butoxy]phenyl-10,15,20-triphenyl porphyrin(o-ImBPTPP),and its iron(Ⅲ) coordination compound(Fe(Ⅲ)(o-ImBPTPP)Cl) were synthesized and identified by elementary analysis and mass spectrometry.The structures were confirmed by IR、1H NMR and UV-vis spectrometries.The coordinations of Fe(Ⅲ)(o-ImBPTPP) Cl with some nitrogeous ligands were studied.Usually Fe(Ⅲ)(o-ImBPTPP)Cl formed low-spin six-coordinate adducts with nitrogeous,but it could form a stable high-spin five-coordinate adduct with imidazole in benzene when the concentration of imidazole was lower.
