Substitution (CH3, Cl, or Br) effects of the imidazolate linker on benzene adsorption kinetics for the zeolitic imidazolate framework (ZIF)-8

Substitution effects of the imidazolate linker affects significantly benzene adsorption kinetics. In particular, methyl groups play an important role in the energetic advantage when the benzene molecule passes through the 6-membered ring aperture.
