Abstract

A formation of supramolecular host–guest inclusion surface layer is reported. A nanostructure of this layer consists of an inclusion complex, where a guest molecule – coumarin-6 (3-(2-benzothiazolyl)-7-(diethylamino) coumarin, C 20H 18N 2O 2S) is placed into a ‘bucket’ of a host molecule – thiolated cyclodextrin (6-monodeoxy-6-monothio-β-cyclodextrin, C 42H 70O 34S) which is attached on Au surface. The inclusion and the layer formation are determined by using time-resolved fluorescence anisotropy, second-harmonic generation (SHG), and fluorescence in combination with laser-induced thermal desorption from the surface.
