Microgels are exiting functional macromolecules and of scientific interest for many years. The controlled integration of chemical functionalities into microgels allows generation of functional polymer systems with unique functions like stimuli-responsiveness, re-shaping, switchability and adaptability.<br/>In this context the integration of cyclodextrin groups into microgels provides functional supramolecular functional tools for the design of new polymer systems. In this paper we describe synthesis of reactive mono and multifunctional cyclodextrins and their controlled incorporation into microgels. Microgels with tunable content and type of cyclodextrins were synthesized and their behavior in aqueous solutions was investigated.<br/>Microgels functionalized with cyclodextrins exhibit interesting complexation properties and can serve as containers for hydrophobic compounds. The accessibility of the cyclodextrins can be regulated by their attachment to the microgel network and crosslinking degree.<br/>Supramolecular cyclodextrin-based crosslinkers were synthesized and integrated into microgels by precipitation polymerisation. Obtained microgels are stable in aqueous solutions and can be easily degraded upon addition of the molecular triggers.<br/>Cyclodextrins in combination with catalytically active gold nanoparticles integrated into microgels play a role of binding domains improving the selectivity of the catalytic processes.
