Posttreatment of pristine metal–organic frameworks (MOFs) with suitable vapor may be an effective way to regulate their structures and properties but has been less explored. Herein, we report interesting example in which a crystalline nonporous Eu(III)-MOF was transferred porous amorphous MOF (aMOF) via iodine adsorption–desorption posttreatment, the resulting aMOF showed improved turn-on sensing respect Ag+ ions. The Eu-MOF, namely, Eu-IPDA, assembled from Eu(III) 4,4′-{4-[4-(1H-imidazol-1-yl)phenyl]pyridine-2,6-diyl}dibenzoic acid (H2IPDA) exhibited two-dimensional (2D) coordination network based on one-dimensional secondary building blocks. close packing 2D networks gives rise three-dimensional supramolecular framework without any significant pores. Interestingly, Eu-IPDA could absorb molecules when crystals were placed at 85 °C, adsorption capacity 1.90 g/g, is comparable those many MOFs large BET surfaces. attributed strong interactions among molecule, carboxy group, N-containing group leads amorphization framework.
