✦ Synopsis

Abstract

magnified image Cyclophanes based on 2,2′‐biimidazole and 2,2′‐bibenzimidazole were synthesized as receptors. UV spectroscopic titration in chloroform at 25°C showed 1:1 complexes between the cyclophanes and the guests, and the binding constants (K) and Gibbs free energy changes (−Δ__G__~0~) were calculated according to the modified Benesi‐Hildebrand equation. J. Heterocyclic Chem., 00, 00 (2009).
