Polymer luminescent compositions based on polystyrene (PS), polycarbonate (PC) and polymethyl methacrylate (PMMA) doped with boron difluoride dibenzoylmethanate (DBMBF2), boron difluoride anthracenoylacetonate (AntAcBF2) and their mixture were investigated. Composition based on PS has a maximum quantum yield of luminescence. The role of PS in increasing the efficiency of energy transfer from the donor (DBMBF2) to the acceptor (AntAcBF2) is revealed, which is due to the formation of exciplexes between DBMBF2 and phenyl rings of PS.
