Abstract

Two simple cationic anthraquinone derivatives were found to form stable complexes with the cucurbit[7]uril host, in which the anthraquinone residue is included by the host cavity. The corresponding equilibrium association constants were relatively low (K ∼10³ M^-1) - compared to those of other complexes formed by the same host - suggesting that anthraquinone is not an ideal guest. However, the electrochemical behavior of the guests is strongly affected by inclusion inside the host cavity.
