| Abstract
| - The interaction of a macrocycle containing three trans-(1R,2R)-diaminocyclohexane units connectedby p-xylene spacers with the isomers 1,3,5-benzenetricarboxylic (1,3,5-BTC), 1,2,4-benzenetricarboxylic (1,2,4-BTC), and 1,2,3-benzenetricarboxylic (1,2,3-BTC) acids and their relevant anions isstudied by means of potentiometric and NMR analysis. The interaction is highest for the isomer1,3,5-BTC, which perfectly fits within the macrocyclic cavity of the host species. The studies havebeen extended to the triacid 1,3,5-benzenetriacetic observing in this case the effect of a size mismatchbetween host and guest species.
