Nanoporous tin(<scp>IV</scp>) chalcogenides: Flexible open‐framework nanbmaterials for chemical sensing

Abstract

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.
