Postsynthetic bromination of UiO-66 analogues: altering linker flexibility and mechanical compliance

Abstract

A new member of the UiO-66 series of zirconium metal–organic frameworks (MOFs) is reported, and the postsynthetic bromination of its integral alkene moeities in a single-crystal to single-crystal manner is fully characterised. Nanoindentation is used to probe the bromination of unsaturated carbon–carbon bonds, in it and an analogous Zr MOF, which leads to more compliant materials with lower elastic moduli.
