Abstract

Synthesis and Binding Behavior of an Artificial Receptor Based on "Upper Rim" Functionalized Calix [5]arene.-Binding studies demonstrate that the new calix[5]arene possessing two benzoic acid moieties shows a prominent shape selectivity. The selectivity is related to structural change in the host-guest complexes. Cyclic hydrogen bonds of the host play an important role in the guest binding. -(HAINO, T.; MATSUMURA, K.; HARANO, T.; YAMADA, K.; SAIJYO, Y.; FUKAZAWA, Y.; Tetrahedron 54 (1998) 40, 12185-12196; Dep.
