Amplification of Negative Gas Adsorption in a multivariate framework

Abstract

The approach of multivariate MOFs was used to fine-tune the mechanical properties of the flexible framework DUT-49. In situ XRD, NMR and physisorption studies showed that the partial incorporation of a more rigid linker into DUT-49 framework enables a stabilization of the metastable open pore phase which led to a twofold amplification of the expelled gas amount upon “Negative Gas Adsorption” transition.
