Harnessing Lewis acidic open metal sites of metal–organic frameworks: the foremost route to achieve highly selective benzene sorption over cyclohexane

Based on the tactical utilization of the Lewis acidic open metal sites (OMS) functionality; for an OMS-rich, microporous, water-stable series of metal–organic frameworks (M-MOF-74), vapor sorption based efficient selectivity for benzene over cyclohexane has been realized, crucial from industrial separation frontier.
