Crystallising MOFs

Research carried out on solvothermal crystallisation of metal-organic frameworks is published as a science highlight at Diamond Light Source.

The work was carried out by Richard Walton in collaboration with colleagues from the Universities of Oxford and Cambridge and from National Institute for Materials Science in Japan. Using high energy X-rays at Diamond Light Source, the UK synchrotron radiation facility, it has proved possible to penetrate solvothermal reaction vessels and measure high resolution powder diffraction data during the formation of extended solid structures, such as metal organic frameworks. This has provided unprecedented information about the formation mechanism of these topical materials, including direct observation of phase transformation and exchange of solvent within porous structures during chemical reaction.

 

The work has been published in two papers in the journal Angewandte Chemie in the past few months:

 

In situ observation of successive crystallizations and metastable intermediates in the formation of metal-organic frameworks. Angew Chem Int Ed. 2016. DOI: 10.1002/anie.201508763.

 

Exchange of Coordinated Solvent During Crystallisation of a Metal–Organic Framework Observed by In Situ High Energy X-ray Diffraction. Angew Chem Int Ed. (2016) DOI: 10.1002/anie.201600896.
