Caging cages : Crystals of a metal‐organic framework, MOF‐123 [Zn 7 O 2 (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 [Zn 7 O 2 (NBD) 5 ]. Moreover, addition of DMF into MOF‐246 triggers reverse transformation to give MOF‐123. NBD=2‐nitrobenzene‐1,4‐dicarboxylate.
