Post-synthetic metal-ion metathesis in a single-crystal-to-single-crystal process: improving the gas adsorption and separation capacity of an indium-based metal–organic framework

By means of post-synthetic metal-ion metathesis, Cu ions selectively substitute In ions in the paddlewheel of JLU-Liu40-In to construct JLU-Liu40-In/Cu, which has significant improved the ability of thermal stability and gas sorption and separation.
