Abstract: Interactions between amines and chiral zinc bisporphyrin linked with flexible alkyl chain containing phenylalanine (±)-1 were investigated by circular dichroism(CD) and UV-V is spectroscopic titration method. CD and UV-Vis 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.
