Nanoporous tin(IV) chalcogenides: Flexible open-framework nanbmaterials for chemical sensing


  • The generous financial assistance of the Natural Sciences and Engineering Research Council of Canada (NSERC), Universal Oil Products (UOP) and the Canadian Space Agency (CSA) is deeply appreciated. Graduate scholarships from NSERC (CB) and the University of Toronto (CB, TJ) are very much appreciated.


Nanoporous sensor materials based on tin chalcogenides are shown to respond to be absorption of guest molecules by a measurable deformation of their open-framework structures which results in changes in heir optical absorption properties. The magnitude and type of deformation depends on the identity of the guest species. The materials and their response to a variety of guests are described.
