叶绿素、血红素、维生素B_(12)等都是不对称的金属卟啉类化合物叫,1975年Anton等首次合成了几种不对称取代四苯基卟啉及其金属配合物.其后,Leznoff,Molinaro等也发表了有关工作.我们模拟叶绿素的结构合成了三个系列13个具有不同长度碳链的单取代四苯基卟啉及其铜、锌、钴、镍等金属配合物(图1).用元素分析、红外光谱、可见吸收光谱和核磁共振谱等表征了它们的可能结构. Chlorophyll, heme, vitamin B_ (12) are asymmetric metalloporphyrins called Anton for the first time in 1975 synthesized several asymmetric substituted tetraphenylporphyrin and its metal complexes .After that, Leznoff , Molinaro et al also published the work.We simulate the structure of chlorophyll synthesis of three series of 13 carbon chains with different lengths of single-substituted tetraphenylporphyrin and copper, zinc, cobalt, nickel and other metal complexes (Figure 1 ). Their possible structures were characterized by elemental analysis, infrared spectroscopy, visible absorption spectroscopy and nuclear magnetic resonance spectroscopy.
