The spectral and generation parameters of coumarin class dyes and the formation mechanism of their inclusion complexes (ICs) with β-cyclodextrin (β-CD) have been studied. Formation of ICs was accompanied by a significant shift of the absorption and fluorescence spectra. The mechanism of complex formation of coumarins with β-CD has been established based on quantum-chemical calculations and absorption-band assignments in the IR spectra. The studied ICs of coumarins with β-CD were shown to have a characteristically higher generation efficiency and photostability and could be considered new active media for tunable dye lasers, the generation efficiency and photostability of which are higher than those of the initial dyes.
