Control of micro- and meso-porocity in metal-organic frameworks

Abstract

Non-interpenetrated three-dimensional metal-organic framework (MOF) with hms topology is converted to doubly interpenetrated analogues with hms-c topology by thermal treatment. Depending on thermal treatment condition and the property of the neutral pillaring linker, the defects of the MOFs can be potentially controlled. Combination of non-stoichiometric removal of neutral pillaring linkers from MOFs and partial collapse of two-dimensional sheets could lead to new hierarchically porous interpenetrated MOFs that contain both micro- and mesopores simultaneously.
