•Three fluorophores were placed in polymer matrices of different polarity: PMMA, PS, PC.•Influence of the matrix on UV–VIS absorption, excitation and emission spectra is examined.•Luminescence decay time is determined from time-resolved fluorescence spectra.•Experimental data is supplemented with TDDFT calculations of theoretical spectra.
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.
