Multifunctional Anionic MOF Material for Dye Enrichment and Selective Sorption of C2 Hydrocarbons over Methane via Ag+-Exchange

The anionic Zn-2,5-thiophenedicarboxylate framework material (1) built from the connection of Johnson cages can perform Ag+-exchange to upgrade the uptakes of C-2 hydrocarbons (C(2)s) and separation properties of C(2)s over methane (C-1). Moreover, its activated phase (1a) can enrich organic dyes from ethanol and make a significant red-shift in photoluminescent spectra of Rhodamine B (Rh B) via varying the aggregation states of dye molecules.
