    New conjugated copolymers containing 9,9-dioctylfluorene and terephthalate units (as dimethyl ester or free acid) were synthesized by the Suzuki coupling and characterized by GPC and NMR, FT-IR and UV-VIS spectroscopy. These copolymers proved to be good luminescent materials showing emissions in the blue region of the visible spectrum both in solution and in thin layers. The copolymers were tested as active layers in light-emitting devices and the formation of their Eu(III) complexes was studied.

    Byly syntetizovány (Suzuki coupling) a charakterizovány (GPC, NMR, FT-IR, UV-VIS) nové konjugované kopolymery obsahující 9,9-dioktylfluorenové a tereftalátové (jako dimethylester nebo volná kyselina) monomerní jednotky. Tyto kopolymery se ukázaly být dobrým luminiscenčním materiálem a to jak v roztoku, tak v tenkých vrstvách. Kopolymery byly použity jako aktivní vrstvy ve světlo emitujících organických diodách a byla také popsána tvorba komplexů těchto kopolymerů s Eu(III).
