An ordered self-assembly of gold nanoparticles (AuNPs) onto microcrystal faces of a 2α-cyclodextrin–dodecanethiol (2αCD–DDT) inclusion compound (IC) by means of a magnetron sputtering technique was obtained. The preferential deposition on the (001) plane of the αCD IC crystal occurs because –SH groups from the guest molecules found within the αCD protrude into that plane. These –SH groups form a two-dimensional hexagonal lattice that interacts with the metal NPs, arranging them in an ordered way.
