主　　题：porous liquids like dissolves like CO_(2)capture low viscosity 

摘      要：Porous liquids(PLs),an emerging porous material with permanent cavities,have attracted extensive attention in recent ***,the current construction methods are complicated and resulting PLs possess high viscosity values,which cannot meet the requirements of practical industrial ***,we demonstrate a generalizable and simple strategy to prepare type III PLs with low viscosity based on the rule of“like dissolves like.Specifically,the monoglycidyl ether terminated polydimethylsiloxane(denoted by E-PDMS)is attached to the surface of Universitetet i Oslo(UiO)-66-NH_(2)via covalent linkage,constructing the pore generator(UiO-66-NH_(2)-E-PDMS,denoted by P-UiO-66).Then,P-UiO-66 is dispersed into different types and amounts of sterically hindered solvents(PDMS400 or PDMS6000),obtaining a series of type III PLs(denoted by P-UiO-66-PLs)with permanent cavities and low *** gas sorption-desorption test shows that P-UiO-66-PLs have an enormous potential for CO_(2)/N_(2) selective ***,the porosity of P-UiO-66-PLs and the CO_(2)sorption mechanism are demonstrated by molecular ***,the generality of the synthesis strategy is confirmed by the successful construction of PLs using two other amino-metal-organic frameworks(MOFs)(MIL-53(Al)-NH_(2)and MIL-88B(Fe)-NH_(2)).Importantly,it’s worth noting that the strategy based on the rule of“like dissolves likesheds light on the preparation of other types of PLs for task-specific applications.
