A polyether amine modified metal organic framework enhanced the CO2 adsorption capacity of room temperature porous liquids.

Based on both the compatibility principle of similar polymeric structures and the steric interaction, a polyether amine (D2000) modified MOF (UIO-66) was dispersed into an ionic liquid with a polyether structure to form a new porous liquid (called the UIO-66-liquid) at room temperature. This unique UIO-66-liquid showed an outstanding CO2 uptake capacity among the existing porous liquids. [ABSTRACT FROM AUTHOR]
