- Abstract
- Polymer luminescent compositions based on polystyrene and polycarbonate doped with symmetrical and asymmetrical curcuminoids of boron difluoride were obtained. The effect of substituents in dye molecules, polymer matrix and phosphor concentration on the spectral properties of polymer composites was studied. With an increase in the electron-donor effect of substituents, a bathochromic shift of the luminescence maxima of symmetric and asymmetric phosphors is observed. Positive solvatochromism for boron difluoride curcuminoids in polymers manifests itself for asymmetric curcuminoids. For films, a bathochromic shift of luminescence is observed with an increase in the phosphor concentration from 0.01 to 0.5%. In a PC film doped with a symmetric dye with a methoxy group, delayed fluorescence due to the formation of excimers was detected at room temperature.
