A 3D microporous covalent organic framework with exceedingly high C3H8/CH4 and C2 hydrocarbon/CH4 selectivity

Here we present a new 3D microporous COF with a uniform pore size (0.64 nm). MCOF-1 exhibits high adsorption selectivity towards C3H8, C2H6 and C2H4 over CH4 owing to the pore size and preferential adsorption.
