Abstract

A water-soluble bowl-shaped host, M3M, which possesses a hydrophobic binding cavity for apolar guests was prepared by metal-induced self-assembly through complexation of L-serine derived hydroxy acid groups with metals. Compound 5 without a xylenic linker was synthesized to investigate the entropy effect on the formation of the self-assembled host. M3M-guest association constants for three aromatic hydrocarbons weremeasured by solubility titrations. No extraction of any guests through [5(2-) + M2+] aqueous solution indicated the entropic disadvantage in the formation of the self-assembled structure. The transport of neutral arenes through an aqueous phase of M3M was studied in a U-type cell. (C) 1998 Elsevier Science Ltd. All rights reserved.
