With the aim to investigate the influence of the ring size of cyclodextrin molecules in polymeric inclusion compounds (polypseudorotaxanes, pseudopolyrotaxanes) on the behavior of the corresponding supramolecular structures at surfaces, solutions of poly(decamethylenedimethylammonium) (PDDA) alone and in the presence of alpha-cyclodextrin (alpha-CD), beta-cyclodextrin (beta-CD), or both alpha-CD and beta-CD were allowed to stand for various times during which polymeric inclusion compounds formed. The so obtained solutions were subsequently exposed to delaminated muscovite mica, the surface of which was saturated either with lithium or, occasionally, potassium ions (called Li-mica or K-mica, respectively). Li-mica was better suited for quantitative evaluations. Basically, muscovite surfaces shift the equilibrium of the inclusion complexes previously established in solution entirely or almost entirely to the side of the free components upon adsorption. However, the equilibrium was not installed after adsorption in the system PDDA/alpha-CD where the release of cylcodextrin was virtually prevented in the presence of alpha-CD for kinetic reasons. Most successful was the anchoring of cyclodextrins when the release of beta-CD was prevented by alpha-CD molecules that occupied the ends of the PDDA chains.
