Abstract
Polymeric luminescent compositions based on polycarbonate and polystyrene doped with β-ketoiminates of boron difluoride were obtained. The luminescent properties of 12 dyes with different substituents were investigated. The influence of the concentration of boron difluoride βketoiminates on the spectral properties of the samples was studied. It was found that the investigated dyes are characterized by monomeric luminescence even at tenfold increase of luminophore concentration (0.05–0.5%). It was found that compositions containing the dyes 3-amino-1-phenyl-2-buten-1-oneate of boron difluoride (1a) and 3-amino-1-phenyl-2-buten-1-oneate of boron difluoride (2a) exhibit exciplex luminescence in polystyrene.
