摘要：

(Figure Presented) A complex situation: Two different types of neutral guest molecules are recognized through a combination of noncovalent interactions by a hydrogen-bonded receptor which displays two different modes of complexation: nonselective-exo and selective-endo complexation (see schematic representation). Furthermore, the hydrogen-bonded trimer can be selectively released. © 2005 Wiley-VCH Verlag GmbH & Co. KGaA.
