Molecular recognition of amines by phenylalanine bridged chiral zinc bis-porphyrin receptor

Interactions between amines and chiral zinc bis-porphyrin linked with flexi ble alkyl chain containing phenylalanine (+/-)-1 were investigated by circu lar dichroism(CD) and UV-Vis spectroscopic titration method, CD and UV-Vis spectra of phenylalanine bridged chiral zinc bisporphyrin changes quite dif ferently with the addition of propylamine and ethylenediamine in chloroform at room temperature. Our results indicate that phenylalanine bridged chira l zinc bis-porphyrin is a potential "CD probe" of the functional group reco gnition for monoamine and diamine molecules as well as "CD probe" of the si ze specific recognition for alpha,omega-diamines.
