  辅助配体对咔唑树枝状分子官能化的杂铱绿色铱树枝状聚合物性能的影响

  摘要：

  合成了一系列用咔唑树枝状官能化的绿色铱铱树枝状大分子，如G2（pic）和G2（acac），其中吡啶甲酸和乙酰丙酮分别用作辅助配体。与相应的铱金属树枝状大分子G2（8％）相比，这些杂合子可以在温和的条件下制备，总收率高达55-67％。树枝状聚合物G2（pic）和G2（acac）均显示亮绿色发射，在甲苯溶液中的光致发光量子产率高于0.80。结果，G2（pic）的最大外部量子效率为7.1％（21.0 cd / A），G2（acac）的最大外部量子效率为7.7％（25.8 cd / A）。已经基于非掺杂的器件配置实现了。最新的性能表明，杂化树状大分子可以成为用于非掺杂电致磷光器件的有前途的候选物，特别是考虑到大规模合成的简便性时。

  Dendrimeric Pt(II) complexes [((CN)-N-boolean AND)Pt(dpm)] and [Pt((CN)-N-boolean AND)(2)] (Hdpm = dipivaloylmethane, (HCN)-N-boolean AND = 1,2-diphenylbenzoimidazole and its derivatives containing the carbazole. dendrons) have been synthesized and characterized systematically. All of the complexes display green emission in the range of 495-535 nm that originated from the 360-440 nm absorption bands, which are assigned to d pi(Pt)->pi*(L) metal-to-ligand charge transfer (MLCT) mixed with intraligand pi(L)->pi*(L) transition. Solution photoluminescence quantum yield (phi(p) 0.26-0.31) of the heteroleptic complexes [((CN)-N-boolean AND)Pt(dpm)] obviously increases when compared with that of complex [((CN)-N-boolean AND)Pt(acac)]. Organic light-emitting diode devices based on these Pt(II) complexes with a multilayer configuration were fabricated and gave desirable electroluminescent (EL) performances, such as non- or less red-shifted EL spectra, in comparison with the photoluminescence spectra and slow efficiency roll-off with increasing brightness or current density. Complex [(t-BuCzCzPBI)Pt(dpm)] (where t-BuCzCzPBI = 1-(4-(3,6-di-(3,6-di-t-butylcarbazol-9-yl))carbazol-9-yl)phenyl-2-phenylbenzoimidazole) showed the best performance, with a maximum current efficiency of 29.31 cd/A and a maximum external quantum efficiency (EQE) of 9.04% among the fabricated devices. Likewise, for homoleptic [Pt(t-BuCzCzPBI)(2)] dendrimer, the powder phi(p) (0.14) and maximum EQE (0.74%) improve by 7 and 7.4 times, respectively, as high as they do for nondendrimeric [Pt(1,2-diphenylbenzoimidazole)(2)] (0.02, 0.10%), although its efficiency is still lower than that of the heteroleptic counterpart due to the severely distorted square-planar geometry of the emitting core. These results reveal that large steric hindrance from ancillary ligand (dpm) or the homoleptic conformation can effectively inhibit intermolecular interaction for these denchimeric Pt(II) complexes.

  The rational design, synthesis and characterization of five phosphorescent platinum complexes [(C boolean AND N) Pt(acac)] [Hacac = acetylacetone, HC boolean AND N = 1-methyl-2-(4-fluorophenyl)benzoimidazole (H-FMBI), 1-methyl-2-phenylbenzoimidazole (H-MBI), 1,2-diphenyl-benzoimidazole (H-PBI), 1-(4-(3,6-di-t-butylcarbazol-9-yl)) phenyl-2-phenylbenzoimidazole (t-BuCz-H-PBI), and 1-(4-(3,6-di-(3,6-di-t-butyl-carbazol-9-yl))carbazol-9-yl) phenyl-2-phenylbenzoimidazole (t-BuCzCz-H-PBI)] have been discussed. The crystal structure of (MBI) Pt(acac) shows a nearly ideal square planar geometry around Pt atom and the weak intermolecular interactions with pi-pi spacing of 3.55 angstrom. All of the complexes emit green phosphorescence from the metal-to-ligand charge-transfer (MLCT) excited state with high quantum efficiency (0.08-0.17) at room temperature. A multilayer organic light-emitting diode (OLED) with (MBI) Pt(acac) as phosphorescent dopant was fabricated using the method of high-vacuum thermal evaporation, which gives a maximum brightness, luminous and power efficiency of 13 605 cd/m(2), 15.1 cd/A and 4.3 lm/W, respectively. In contrast, the comparable performance can be achieved in the solution-processed OLED based on (t-BuCzPBI) Pt(acac) with a peak brightness, luminous and power efficiency of 13 606 cd/m(2), 17.5 cd/A and 8.4 lm/W, respectively. The better device efficiency results from the good square plane of central Pt coordination unit and the inhibition of the aggregates due to bulky and rigid t-butylcarbazole dendrons.
