A new strategy for constructing a disulfide-functionalized ZIF-8 analogue using structure-directing ligand–ligand covalent interaction†
Abstract
Inter-ligand van der Waals forces play a key role in the synthesis of different ZIF types. Here we report an unusual case involving covalent inter-ligand interactions through disulfide bond formation in a ZIF-8 analogue. It exhibits high CO2 uptake and stepwise adsorption of light hydrocarbons with potential applications in ethane/ethylene separation.
