Mechanically Planar Chiral [2]Rotaxanes for Multistate Circularly Polarized Luminescence Switching

A Wiley journal article published 2026-09-30 reports research on chiral rotaxane molecules capable of multistate switching of circularly polarized luminescence. The source record is a journal article entry and provides no additional experimental or impact details.

Some modes of motion present in some simple building blocks of artificial molecular machines. a) Rotation around single bonds and in sandwich-like p-metal complexes. b) Bending as a consequence of double-bond isomerization. c) Translational motion of a ring along the dumbbell of a rotaxane. d) Circumrotation motion of rings in a catenane. Based on figure from ChemPhysChem 2016, 17,1780–1793 (image self-made using ChemDraw, inspired from publication, doi:10.1002/cphc.201501155)
