Description
Martina Vachtlová and ten co-authors make six new light-switch compounds in a 2026 chemistry paper. The compounds are halogenated azobenzene acrylates, which change shape when light hits them. Adding fluorine, chlorine, or bromine atoms lets chemists tune how they switch. The team made the compounds in three steps and tested them in depth.
Single-halogen types switched best in liquid, with up to 93 percent shape change. Types with two halogens switched less, due to their bent shape. One fluorine type kept a clear color change in a plastic film for over 90 days. The team says halogen choice is a strong tool for tuning such materials. Uses may include heat sensors that change color and light-run devices.
