Description
Summary:Luminescent polymer composites based on polycarbonate and polystyrene doped with boron difluoride β-ketoiminates have been synthesized. The luminescence properties of 12 dyes with various substituents have been studied. The effect of the boron difluoride β-ketoiminate concentration on the spectral properties of the samples has been studied. It has been found that the studied dyes exhibit monomer luminescence even with a tenfold increase in the luminophore concentration (from 0.05 to 0.5%). It has been revealed that composites containing boron difluoride 3-amino-1-phenyl-2-buten-1-onate (1a) and boron difluoride 3-methylamino-1-phenyl-2-buten-1-onate (2a) dyes in polystyrene exhibit exciplex luminescence.
