Entropic separations of mixtures of aromatics by selective face-to-face molecular stacking in one-dimensional channels of metal-organic frameworks and zeolites

Abstract

Separation of challenging mixtures using metal-organic frameworks can be achieved by an entropy-driven mechanism, where one of the components can arrange into a "face-to-face" stacking, thus reducing its "footprint" and reaching a higher saturation loading.

Keywords: MOFs; aromatic compounds; entropy; mixtures; separation.
