DESIGNING POROSITY IN COORDINATION SOLIDS

摘要

Two strategies for producing porous coordination solids are described. The first deals with the construction of rigid metal-organic frameworks using ligands having multidentate functionalities, and shapes that prevent interpenetration. These ligands are chosen to enhance the selective inclusion of certain guest molecules. The second strategy addresses the character of the guest species that occupy the channels of the metal-organic framework. Here, hydrogen-bonded aggregates have been designed as guest species not only to allow the formation of large voids but also to facilitate the removal of inclusions, thus permitting access into the channels by other molecular species.
