Reversible Interpenetration in a Metal-Organic Framework Triggered by Ligand Removal and Addition

Caging cages: Crystals of a metal‐organic framework, MOF‐123 [Zn7O2(NBD)5(DMF)2] have a three‐dimensional porous structure in which DMF ligands (see picture, pink) protrude into small channels. Removal of these ligands triggers the transformation of this MOF to the doubly interpenetrating form, MOF‐...

Summary:Caging cages: Crystals of a metal‐organic framework, MOF‐123 [Zn7O2(NBD)5(DMF)2] have a three‐dimensional porous structure in which DMF ligands (see picture, pink) protrude into small channels. Removal of these ligands triggers the transformation of this MOF to the doubly interpenetrating form, MOF‐246 [Zn7O2(NBD)5]. Moreover, addition of DMF into MOF‐246 triggers reverse transformation to give MOF‐123. NBD=2‐nitrobenzene‐1,4‐dicarboxylate.
