Abstract

An aminal tying method was applied to post-synthetically modify a flexible organic cage, RCC1, to construct a porous ionic liquid (PIL). The resulting PIL, [RCC1-IM][NTf2]6, displayed melting behaviour below 100 °C, a transition to a glass phase on melt-quenching, CO2 uptake, and its permanent porosity was confirmed using molecular dynamic simulations.
