MethodExperimental Chemistry and Materials Science

ProcedureResearchers developed a photoswitchable system where a dithienylethene molecule, acting as a light-sensitive switch, controls the reactivity of conjugate addition-elimination reactions. This allowed for the dynamic attachment and detachment of various chemical groups (nucleophiles) to a core structure. The system was then applied to modify surfaces, control self-assembling structures, and create/degrade polymers using light.
