abstract = "The microscopic dielectric constant of the cyclodextrin (CD) interior is a fundamental property of these microheterogeneous environments. Polarity and dielectric constant play a crucial role in the understanding of spectroscopy and chromatography. Bulk measurements of these properties are not suitable for the evaluation of inclusion cavities, and frequently luminescent probes are employed to estimate these parameters. Recently, polycyclic aromatic hydrocarbon probes have been used to evaluate the effective polarity of the CD cavity, and the approximate formation constants were estimated for inclusion complexes of the variety:PAH + CD ⇌ [PAH − CD] (1)[PAH − CD] + CD ⇌ [CD − PAH − CD] (2)[PAH − CD] + PAH ⇌ [PAH − PAH − CD] (3)[PAH − CD] + [PAH − CD] ⇌ [CD − PAH − PAH − CD] (4)",
