Metal–organic frameworks utilising an interlocked, hexadentate linker containing a tetra-carboxylate axle and a bis(pyridine) wheel

Abstract

A mechanically interlocked ligand which combines an H-shaped axle containing four terminal 3-carboxyphenyl groups and a macrocyclic wheel with two 4-pyridyl groups was used to create Zn(<sc>ii</sc>) and Cu(<sc>ii</sc>) metal–organic framework materials that contain unique frameworks threaded solely due to the interpenetrated nature of the linker.
