摘要:
An ordered self-assembly of copper, silver and gold nanoparticles onto crystal faces of alpha-cyclodextrin/1-octanethiol and 2 alpha-cyclodextrin/1-octylamine inclusion complexes by means of physical vapor deposition (magnetron sputtering) has been achieved. The preferential deposition on the (001) plane of the supramolecular crystal occurs because the -SH and -NH2 groups from the guest molecules found within the alpha-cyclodextrin protrude into that plane. These functional groups form a two-dimensional hexagonal lattice that interacts with the metal nanoparticles, arranging them in an ordered way. (C) 2011 Elsevier B.V. All rights reserved.
