  High-Efficiency Green Organic Light-Emitting Devices Utilizing Phosphorescent Bis-cyclometalated Alkynylgold(III) Complexes

  摘要：

  A new phosphorescent material of cyclometalated alkynylgold(III) complex, [Au(2,5-F2C6H3-C boolean AND N boolean AND C)(C=-D-C6FH4N(C6H5)(2)-p)] (1) (2,5-F2C6H3-HC boolean AND N boolean AND CH = 2,6-dipheny1-4-(2,5-difluorophenyl)pyridine), has been synthesized, characterized, and its device performance investigated. This luminescent gold(III) complex was found to exhibit rich PL and EL properties and has been utilized as phosphorescent dopants of OLEDs. At an optimized dopant concentration of 4%, a device with a maximum external quantum efficiency (EQE) of 11.5%, corresponding to a current efficiency of 37.4 cd/A and a power efficiency of 26.2 Imm, has been obtained. Such a high EQE is comparable to that of Ir(ppy)3-based devices. The present work suggests that the alkynylgold(III) complex is a promising phosphorescent material in terms of both efficiency and thermal stability, with the additional advantages of its relatively inexpensive cost and low toxicity.

  tridentate ligand‐containing alkynylgold(III) complexes in solid‐state thin films. Interestingly, the energy of the excimeric emission can be controlled by the rational design of the fused heterocyclic alkynyl ligands. Superior solution‐processable organic light‐emitting devices (OLEDs) with high external quantum efficiencies (EQEs) of 12.2, 13.5, 9.3, and 5.2 % were obtained with green, yellow, orange

  A new class of bipolar alkynylgold(III) complexes containing triphenylamine and benzimidazole moieties has been synthesized, characterized, and applied as phosphorescent dopants in the fabrication of solution-processable organic light-emitting devices (OLEDs). The incorporation of methyl groups in the central phenyl unit has been found to rigidify the molecule to reduce nonradiative decay, yielding

  A series of luminescent alkynylgold(III) complexes containing various tridentate bis-cyclometalating ligands derived from 2,6-diphenylpyridine (R-(CNC)-N-boolean AND-C-boolean AND), [Au(R-(CNC)-N-boolean AND-C-boolean AND)(C C-C6H4-R'] has been successfully synthesized and characterized. Complexes 1 and 6 have been determined by X-ray crystallography. Electrochemical studies show a ligand-centered reduction that originated from the tridentate R-(CNC)-N-boolean AND-C-boolean AND pincer ligands and an alkynyl-centered oxidation. The photophysical properties of the complexes have been studied in detail by electronic absorption and emission studies. Tunable photoluminescence behaviors have been observed, with the emission maxima spanning through the visible region from 476 to 669 nm in dichloromethane at room temperature, and the complexes were also found to be emissive in various media at both room and low temperatures. Transient absorption studies have been conducted to investigate the excited state properties of the complexes. Furthermore, selected complexes have been incorporated into the emissive layer (EML) of organic light-emitting devices (OLEDs) and have demonstrated interesting electroluminescence.

  A series of luminescent bis-cyclometalated alkynylgold(III) complexes have been synthesized and characterized. Some of the complexes have been demonstrated to exhibit gelation properties driven by pi-pi stacking and hydrophobic-hydrophobic interactions. The gelation properties have been investigated in detail through variable-temperature UV-vis absorption and emission studies, and the morphology of the gels has also been characterized by scanning electron microscopy and transmission electron microscopy.
