  摘要：

  在这里，我们通过取代吸电子（-CHO，-CF 3和-CN）和给电子（-OMe和- NMe 2）位于吡啶基部分的4'位置，并在吡啶甲酸作为辅助配体的情况下，将它们用于构建五个新的铱（III）配合物（Ir1-Ir5）。为了理解取代基效应，对已开发的铱（III）化合物的光物理性质进行了研究。包含铱（III）化合物（Ir3）的强吸电子（–CN）基团表现出高效的真正绿色磷光（λ最大= 508纳米）在溶液和薄膜室温，用优异的量子效率（Φ PL的分别0.90和0.98，）。在另一方面中，-CF 3基团取代的铱（III）化合物（亮点Ir2）显示器天蓝色发射（λ最大= 468纳米）与有希望的量子效率（Φ PL = 0.88和0.84的溶液和在薄膜， 分别）。所述-CHO取代的铱（III）络合物（IR1）显示黄绿色发射（λ最大= 542纳米）。最重要的是，强电子给体–NMe 2取代的铱（III）络合物（IR5

  An organic electroluminescent compound containing Iridium, preparation method thereof and an organic electroluminescent device are disclosed. The compound is represented by the structure (2), wherein, R is C1˜C4 alkyl. The structure of the compound contains bipyridine ligand, also carries alkoxy group and fluorine atom, which improves its carrier injection and transfer ability, and increases its internal quantum efficiency and electroluminescent efficiency. Furthermore, the compound uses strong field ligand 2-pyridine carboxylic acid as assistant ligand, which causes an effective blue shift of its emission spectrum and increases light-emitting efficiency of blue light phosphorescence greatly.

  Four blue phosphorescent complexes with the general formula (4-R-dfpypy)2Ir(L<^>X), where 4-Rdfpypy 4-alkyl-2',6'-difluoro-2,3'-bipyridine and L<^>X = picolinate or dipivaloylmethanate, were synthesized, and their photoluminescent properties were systematically investigated. All complexes show bright deep-blue phosphorescence emissions with lambda(max) = 440-450 nm and quantum efficiencies of 0.25 - 0.78 in the fluid state. The emission bands of compounds 1-4 are slightly red shifted by 5-10 nm relative to the homoleptic congener, Ir(dfpypy)3. Electroluminescent (EL) devices were fabricated using compound 2 as a dopant, 1,3-bis(N-carbazolyl)benzene (mCP) as the host, and TSPO1 (diphenylphosphineoxide-4-(triphenylsilyl)phenyl) as the electron transporting/exciton blocking layer. These EL devices show a deep-blue color (CIE: x, y = 0.14, 0.17) with high efficiencies. The EL device of compound 2 at a doping level of 5 wt% has the best performance with an EQE of 14.6% at a brightness of 100 cd/m(2) and a current efficiency of 18.3 cd/A. (C) 2015 Elsevier Ltd.
