  • The disassembly of a parent zeolite and its reassembly into two zeolites with targeted topologies is described. This process demonstrates that it is possible to target specific ring sizes in a zeolite by replacing one size of unit in the structure with alternative units of a different size.

  • While aluminosilicate zeolites are of interest for many applications, the affect of water on zeolite stability in mild aqueous conditions has yet to be established. Here, using ab initio calculations and NMR spectroscopy, the authors show that covalent bonds in the zeolite chabazite are labile when in contact with neutral liquid water.

  • The promise shown by metal–organic frameworks for various applications is somewhat dampened by their instability towards water. Now, an activated MOF has shown good hydrolytic stability owing to the presence of weak, sacrificial coordination bonds that act as a ‘crumple zone’. On hydration, these weak bonds are cleaved preferentially to stronger coordination bonds that hold the MOF together.

  • The assembly–disassembly–organization–reassembly (ADOR) process has recently enabled the synthesis of unusual — and sometimes previously inaccessible — inorganic materials. Further insight into its complex mechanism has now been gained that explains the unexpected formation and structure of such a zeolite.

  • Small modifications to the organic linkers in metal–organic framework materials (MOFs) can profoundly change their properties. Now, selective in situ esterification of a carboxylic-acid-based linker leads to a MOF with two types of channel having different surface chemistries. Adsorption into these channels is independent and can be switched using thermal or chemical triggers.
