title: Spectral kinetics of fluorescence spectra of fluoroderivatives of pyrazoloquinoline in different polymer matrices.
abstract: Three fluoro-substituted pyrazoloquinoline derivatives have been placed in polymer matrices: polycarbonate, poly(methyl methacrylate) and polystyrene. Absorption, excitation and time-resolved fluorescence spectra have been recorded and luminescence lifetime of the optically active composites has been determined. Influence of the dielectric environment the optical properties of the chromophores are discussed. Experimental data and conclusions are supported with (TD)DFT calculations.
