Parting the clouds : A supramolecular recognition reaction of cyclodexdrins with polymers—adamantyl derivative N ‐isopropylacrylamide copolymers—with inverse phase behavior is described. The turbidity of the polymer solutions depends upon the cyclodextrin concentration. Competition reactions with potassium‐1‐adamantylcarboxylate show that the inclusion‐complex formation is reversible (see scheme).
