摘要：

MOF constrictor: Covalent modification of a ZIF-90 membrane was achieved by imine condensation of the aldehyde groups of the metal-organic framework (MOF) linker by ethanolamine (see picture). The modification leads to constriction of the pore apertures and prevents unselective permeation through defect pores, thus improving gas separation performance. For a H2/CO2 mixture, selectivity can be increased from 7.3 to 62.5. Copyright © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
