Abstract

A polyoxapolyaza heteroditopic macrobicyclic compound (btpN(4)O(3)) was synthesized. The acid-base behaviour of the compound as well as its binding ability for zwitterionic amino acids were studied by potentiometry at 298.2 +/- 0.1 K in H2O-MeOH (50 : 50 v/v) and at I = 0.10 +/- 0.01 M in NMe4TsO. The H(n)btpN(4)O(3)(n+) showed preference for amino acids containing tetrahedral anionic groups.
