| 2 | Toward Liquid Phase Processable Metal Organic Frameworks:Dream or Reality?显示文摘CONSPECTUS:Conventionally,the virtue of porosity is only given to porous solids.Metal Organic Frameworks(MOFs),carbon materials,or zeolites are some examples.However,processing these solids is not a straightforward task.Here,we discuss how to endow porous solids(MOFs)with liquid phase processability.More specifically,we show that surface modification of MOF crystals can lead to the formation of porous liquids(PLs)that can be further processed in the liquid phase.For instance,when placed in mesitylene,ZIF-67 predictably sediments.In contrast,with the adequate surface modification,stable dispersion of ZIF-67 can be achieved.Our proposed surface modification is facile and rapid.N-Heterocyclic carbenes are chosen as modifying agents as they are similar to imidazole linkers present on ZIFs.A simple stirring of a MOF and carbene mixture results in a modified solid.The morphology and textural properties of the modified MOF do not change from the ones of its parent.Since the porosity in solution remains unoccupied,the obtained stable colloids behave as porous liquids.Research into porous liquids is an emerging field that has already shown great promise in gases storage.Our breakthrough experiments show that these particular PLs have large potential for the separation of CO_(2)/CH_(4)mixtures. | Daria Poloneeva Shuvo Jit Datta Luis Garzon-Tovar Sara Durini Magnus Rueping Mohamed Eddaoudi Anastasiya Bavykina Jorge Gascon | 2021 | Accounts of Materials Research2021，2，12： | 0 |
