抄録
The doubly-protonated 1,4,8,11-tetraazacyclotetradecane-1,4,8,11-tetracarboxylate anion (H2teta2−), 1,4,7,10,13-pentaazacyclopentadecane-1,4,7,10,13-pentacarboxylate anion (H2pepa3−), and 1,4,7,10,13,16-hexaazacyclooctadecane-1,4,7,10,13,16-hexacarboxylate anion (H2heha4−) have been shown to form stable 1 : 1 ratio complexes with amino acids in aqueous solutions. Their association constants, βL, were determined polarographically. The greater association constants obtained indicate that H2teta2− and H2pepa3− anions selectively interact with an amino acid which has a planar aromatic moiety. The results show the importance of hydrophobic interaction, such as CH–π interaction between the aliphatic CH2 residue of acetate pendant of receptor and the planar aromatic moiety of substrate, amino acid, in holding the protonated macrocyclic polyazacycloalkane-poly-N-polycarboxylate anion and amino acid together. Thus, they act as selective receptors for phenylalanine, tyrosine, tryptophan(e), and their derivatives.
