The Influence of the Polymer Matrix on Luminescent Properties of Compositions Doped with Boron Chelates

Resumo

Luminescent polymer compositions based on polystyrene (PS), polycarbonate (PC), and polymethyl methacrylate (PMMA) doped with dibenzoylmethanate boron difluoride (DBMBF₂), anthracene–acetonate boron difluoride (AntAcBF₂), and their mixture have been investigated. The maximum quantum yield of luminescence has been demonstrated by the composition based on PS. The role of PS in increasing the efficiency of energy transfer from the donor (DBMBF₂) to the acceptor (AntAcBF₂) has been established and appeared to be caused by the formation of exciplexes of DBMBF₂ with phenyl rings of PS.
