TOPOLOGY CONVERSION OF NON-INTERPENETRATED THREE-DIMENSIONAL METAL-ORGANIC FRAMEWORKS

Abstract

Non-interpenetrated three-dimensional metal-organic frameworks (MOFs) with both an interpenetrationfavorable (3,5)-c hms topology and an interpenetrationunfavorable (3,5)-c gra topology are converted to doubly interpenetrated analogues with hms-c topology by thermal treatment, even in the absence of solvent. Depending on thermal treatment condition and the property of the neutral pillaring linker, the defects of the MOFs can be potentially controlled. Non-stoichiometric removal of neutral pillaring linkers from MOFs could lead to new interpenetrated hierarchically porous MOFs that contain micro- and mesopores simultaneously.
