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.
