The metal–organic framework (MOF) Cu-BTC has been the subject of extensive study, but now scientists working in the USA and France have found evidence that the material has potentially important redox properties. Previously small quantities of Cu+ observed in the MOF had been attributed to impurities but Szanyi et al. have shown that the ratio of Cu+ : Cu2+ in the framework can be altered by varying the conditions the material is exposed to. This exciting work has been highlighted in phys.org.
