摘要：
Scanning tunneling microscopy on both cyclodextrins (CyDs) and their structural complex formed with a guest compound (1-adamantanemethanol) was performed on specimens obtained by deposition of CyD aqueous solutions onto highly oriented pyrolytic graphite. The CyD and guest compound image sizes were found to be satisfactorily consistent with molecular dimensions. In the absence of guest compounds, both alpha- and beta-CyDs strongly interacted with each other, and formed regularly ordered structures. Guest compound addition resulted in a breakdown of the regular CyD structure, thus indicating that mutual CyD molecular interactions are suppressed by CyD-guest complex formations.
