苯丙氨酸桥联手性锌双卟啉受体对胺的分子识别

Molecular Recognition of Amines by Phenylalanine Bridged Chiral Zinc Bisporphyrin Receptor

金属卟啉的分子识别研究是当今卟啉仿生化学的重要课题．手性金属卟啉作为光学活性分子的对映选择识别受体和手性核磁共振试剂［１］尤为引人注目．Ｃｒｏｓｓｌｅｙ等［２］报道了以刚性Ｔｒｏｇｅｒｓ碱为间隔基的手性锌双卟啉对组氨酸甲酯和赖氨酸苯酯的立体选择性识...

Interactions between amines and chiral zinc bisporphyrin linked with flexible alkyl chain containing phenylalanine () 1 were investigated by circular dichroism(CD) and UVVis spectroscopic titration method. CD and UVVis spectra of phenylalanine bridged chiral zinc bisporphyrin changes quite differently with the addition of propylamine and ethylenediamine in chloroform at room temperature. Our results indicate that phenylalanine bridged chiral zinc bisporphyrin is a potential CD probe of the functional group recognition for monoamine and diamine molecules as well as CD probe of the size specific recognition for ,diamines.
