- 論文の詳細を見る
The formation process of a typical host–guest compound, $\beta$-cyclodextrin–ferrocene system, in various solutions was analyzed on the basis of the results of unbinding-force measurement using atomic force microscopy (AFM). The ratio of the formation numbers determined by AFM is consistent with the complexation constant obtained from the macroscopic analysis. We also analyzed the unbinding force on the basis of the mechanism of surface tension, and solvophobic factors, the intrinsic van der Waals interaction and the effective length of surface tension for ferrocene, were evaluated at the single-molecule level.
