  Two novel orange cationic iridium(III) complexes with multifunctional ancillary ligands used for polymer light-emitting diodes

  摘要：

  Two novel orange cationic iridium complexes [(npy)(2)Ir(o-phen)]PF6 and [(npy)(2)Ir(c-phen)] PF6 were synthesized. Hnpy: 2-(naphthalen-1-yl) pyridine; o-phen: a 1,10-phenanthroline derivative containing an electron-transporting functional group of 2,5-diphenyl-1,3,4-oxadiazole and a crystallization-resistant tert-butyl functional group; c-phen: a 1,10-phenanthroline derivative containing a hole-transporting functional group of carbazole and a crystallization-resistant 2-ethylhexyl functional group. Both of them are amorphous and possess high thermal stability with 5% weight-reduction temperatures (Delta T-5%) of 386 degrees C and 383 degrees C, and glass-transition temperatures (T-g) of 267 degrees C and 195 degrees C respectively. They were used as phosphorescent dopants in polymer light-emitting diodes (PLEDs) fabricated by solution-processed technology with configuration of ITO/PEDOT:PSS/PVK:PBD:iridium complex/TPBI/CsF/Al. At the optimal doping concentration of 2.0 wt%, the corresponding PLEDs exhibited the maximum current efficiencies of 9.1 cd A(-1) and 10.0 cd A(-1), the maximum external quantum efficiencies of 6.5% and 7.1%, and the maximum luminance of 2314 cd m(-2) and 3157 cd m(-2) respectively, with the same CIE coordinates of (0.57, 0.40). The results indicate that cationic iridium complexes are promising candidates for PLED applications when they are designed reasonably. (C) 2012 Elsevier B.V. All rights reserved.

  Cationic iridium(III) complexes with 1,10-phenanthroline (phen) derivatives containing oxadiazole-triphenylamine, oxadiazole or triphenylamine unit used as neutral auxiliary ligands, with the formula of [Ir(ppy)(2)(op-phen)][PF6] (C1), [Ir(ppy)(2)(o-phen)][PF6] (C2), and [Ir(ppy)(2)(p-phen)][PE6] (C3) (ppy = 2-phenylpyridine) were synthesized, respectively. The complexes exhibit high thermal stability and were used as phosphorescent dopants in polymer light-emitting diodes (PLEDs) with the configuration of ITO/PEDOT: PSS/PVK (70): PBD (30): complex (x, wt.%)/TPBI/CsF/Al. The complexes C1, C2 and C3 exhibit high electroluminescent performances with the maximum luminance efficiencies of 30.6 cd/A, 28.4 cd/A and 26.3 cd/A, respectively. The Commission Internationale de L'Eclairage (CIE) color coordinates of all complexes are (0.41, 0.55) corresponding to the yellow-green region. The complex C1 containing bipolar unit of oxadiazole-triphenylamine exhibits higher efficiency due to its balance of hole and electron fluxes. (C) 2013 Elsevier Ltd. All rights reserved.
