Understanding how photoswitchable chiral dopants can control the helical pitch of host liquid crystals will aid the development of smart and adaptive soft materials. Now the molecular-level mechanisms that control the chirality transfer in chiral triptycene-containing bistable hydrazones have been elucidated. This enables the preparation of rewritable multi-coloured liquid crystal canvases.
