Synthesis of a Mechanically Planar Chiral and Axially Chiral [2]Rotaxane

Synthesis of a Mechanically Planar Chiral and Axially Chiral [2]Rotaxane

In this study, we synthesized a [2]­rotaxane that was both mechanically planar chiral and axially chiral, comprising a symmetrical bis-crown ether featuring a biphenyl moiety (as the macrocyclic component) and a symmetrical bis-ammonium salt (as the dumbbell-shaped component).
