Organosilica‐Functionalized Zeolitic Imidazolate Framework ZIF‐90 Membrane with High Gas‐Separation Performance

A clear separation: A post-synthetic functionalization method is reported to obtain a highly permselective zeolitic imidazolate framework (ZIF-90) membrane. The intercrystalline defects of the ZIF-90 membrane are minimized to enhance the separation selectivity while a high permeance is maintained.
