Donor-acceptor-donor type cyclometalated platinum complex liquid crystal luminescent material and application thereof in polymer polarized electroluminescent device
2015
The invention discloses a donor-acceptor-donor type cyclometalated platinum complex liquid crystal luminescent material and application thereof in a polymer polarized electroluminescent device. According to the cyclometalated platinum complex liquid crystal luminescent material, benzophenanthrene derivative is connected to a phenylpyridine-carbazole derivative by means of conjugation or non-conjugation to form a cyclometalated ligand, and a propanedione derivative is employed to form an auxiliary ligand. The cyclometalated platinum complex is adopted as the luminescent layer doping agent, poly(9,9-dioctylfluorene) (PFO) is taken as the host material, and through rubbing alignment and heating annealing, a luminescent layer can be prepared, and the polymer polarized electrogenerated white light-emitting device with a polarization ratio of 1.32 can be obtained.
