  具有激发光致发光特性的P ^ N配体的双核卤化铜（I）配合物的合成，结构和表征

  摘要：

  使用易于获得的二苯基膦基吡啶型P ^ N配体的模块化配体系统，已经以高收率合成了一系列高发光度的双核铜（I）配合物。通过X射线晶体学研究和元素分析对这些配合物进行表征，揭示出具有蝶形金属卤化物核的双核配合物结构。配合物具有发射光谱，覆盖从蓝色到红色的可见光谱，以及高达96％的高量子产率。密度泛函理论计算表明，HOMO主要由金属核和桥接卤化物的轨道组成，而LUMO主要位于P ^ N配体的杂环部分。因此，桥联配体的杂环部分的修饰允许发光波长的系统调节。通过增加N-杂环的芳族体系或通过吡啶基部分的官能化，获得具有在481至713nm处的最大发射的配合物。对于代表性的化合物，已表明可以将环境温度发射指定为热激活的延迟荧光，其特征在于在ϕ时只有6.5μs的极短的发射衰减时间。PL = 0.8。提出将这些化合物应用于OLED中的单重态收获。

  Heteroleptic, Dinuclear Copper(I) Complexes for Application in Organic Light-Emitting Diodes

  摘要：

  A series of highly luminescent, heteroleptic copper(I) complexes has been synthesized using a modular approach based on easily accessible P boolean AND N ligands, triphenylphosphine, and copper(I) halides, allowing for an independent tuning of the emission wavelength with low synthetic efforts. The molecular structure has been investigated via X-ray analysis, confirming a dinuclear copper(I) complex consisting of a butterfly shaped metal-halide cluster and two different sets of ligands. The bidentate P boolean AND N ligand bridges the two metal centers and can be used to tune the energy of the frontier orbitals and therefore the photophysical characteristics, as confirmed by emission spectroscopy and theoretical investigations, whereas the two monodentate triphenylphosphine ligands on the periphery of the cluster core mainly influence the solubility of the complex. By using electron-rich or electron-poor heterocycles as part of the bridging ligand, emission colors can be adjusted, respectively, between yellow (581 nm) and deep blue (451 nm). These complexes have been further investigated in particular with regard to their photophysical properties in thin films and polymer matrix as well as in solution. Furthermore, the suitability of this class of materials for being applied in organic lightemitting diodes (OLEDs) has been demonstrated in a solution-processed device with a maximum current efficiency of 9 cd/A and a low turn-on voltage of 4.1 V using a representative complex as an emitting compound.

  Organic light-emitting diodes (OLEDs) are currently being commercialized for lighting and display applications, but more work has to be done. In addition to the ongoing optimization of materials and devices in terms of efficiency and lifetime, the substitution of processing steps involving vacuum deposition for solution processing techniques is favorable. To reach this aim, good soluble materials are required. A modular family of highly emissive PyrPHOS-copper iodide complexes featuring various ancillary phosphine ligands has been synthesized. Photoluminescence spectroscopy, TCSPC (time-correlated single photon counting), cyclic voltammetry, X-ray diffraction, and DFT calculations were performed to gain a broad understanding of the complexes. While the photophysical properties are consistent within the family, thermal stability and solubility depend on the ligands. The materials showed very high photoluminescence quantum efficiencies up to 99% in powders and 85% in thin films. Selected examples were tested in devices, confirming the suitability of heteroleptic PyrPHOS-complexes for OLEDs.
