Description

Lawson and colleagues published a 2026 study on forcing a dye molecule to twist one way. Perylene diimide dyes can form helices that bend light in useful ways. Most twisted versions flip between hands and lose their special glow. The team used a rotaxane, a ring threaded on an axle, as the guide.

Their rotaxane's built-in twist is stable and cannot flip over time. It pushed the dye into a single-handed helix that stayed put. The dye then showed steady light-bending and glowing effects in tests. The flat dye face also let rotaxanes stack together, a rare trick. Control reached from single molecules up to grouped assemblies alike. Lasting single-handed glow suits sensing, imaging, and catalyst design work.
