SYNTHESIS AND STRUCTURE OF THE NOVEL NANOPOROUS TIN(IV) SULFIDE MATERIAL TPA-SNS-3

The organic-template-mediated synthesis, directly from elemental tin a nd sulfur constituents, and the single-crystal XRD structure of a nove ltin(IV) sulfide-based open-framework material, denoted TPA-SnS-3, is reported for the first time. This structure consists of corrugated nan oporous layers, which can undergo intralayer elastic deformations, as well as interlamellar alterations, in response to the type and the loa ding of the occluded guest molecules. Flexible nanoporous tin(IV) sulf ides of this type, with framework elements the same as those in the we ll-known bulk semiconductor SnS2, are unique and of considerable inter est in the context of designing new generation molecular recognition d evices.
