摘要：
Supramolecular host-guest complex cyclodextrin-diphenylhexatriene as a model of noncovalent binding is studied by means of time-of-flight secondary ion mass spectrometry. Cyclodextrin and diphenylhexatriene are in forms of beta-cyclodextrin (C42H70O35) and 1,6-diphenyl-1,3,5-hexatriene (C18H16), respectively. The whole intact supramolecular host-guest 1:1 complex between cyclodextrin and diphenylhexatriene is observed in cationized forms with Na at 1389.5 m/z and with K at 1405.5 m/z. The focus is on the higher ratio complexes, where the complexes of cyclodextrin-diphenylhexatriene with ratios of 1:2 and 2:1 are observed in cationized forms with Na at 1622 and at 2524 m/z, and with K at 1638 and 2541 m/z, respectively. These complexes are assumed to be basic building blocks of cyclodextrin-diphenylhexatriene nanowire structure. (c) 2006 Elsevier B.V. All rights reserved.
