Structure-dependent and morphology-dependent exchange of guests in permeable molecular crystals
Written by sctunisie no commentsOur understanding of the properties of porous crystalline materials is largely based on studies of zeolites and other inorganic substances. The advent of new analogues, including purely molecular networks, has created opportunities to base knowledge of porous materials on a broader foundation. We have used permeable molecular crystals of tetrakis(3,5-dihydroxyphenyl)silane (1) to show how the exchange of guests depends on both structure and morphology. Specifically, exchange is faster in polymorphs with wider channels and in crystalline morphologies with well-developed faces that cut the channels.
