Abstract

Chemoresponsive microgels functionalized with enantiomeric Δ- or Λ-[Ru(bpy)₃]²⁺ showed tunable chiroptical properties upon swelling and shrinking. The tuning is triggered by a modulation of the local mobility of [Ru(bpy)₃]²⁺ upon addition of fructose, controlling interactions and distances between [Ru(bpy)₃]²⁺ and phenylboronic acid.
