Abstract
A novel metal organic framework, EMM-42, is described having the structure of UiO-66 and comprising bisphosphonate linking ligands. EMM-42 has acid activity and is useful as a catalyst in olefin isomerization. Also disclosed is a process of making metal organic frameworks, such as EMM-42, by heterogeneous ligand exchange, in which linking ligands having a first bonding functionality in a host metal organic framework are exchanged with linking ligands having a second different bonding functionality in the framework.
Claims16
