  Highly regioselective copper catalyzed ortho-chlorination of aryl pyridines was achieved with TBHP as oxidant and 1,2-dichloroethane as chlorinating agent for the first time. Switching the oxidant from TBHP to benzoyl peroxide under identical reaction conditions effects ortho-oxygenation.

• Room-temperature combinatorial screening of cyclometallated iridium(iii) complexes for a step towards molecular control of colour purity

  A library of emission spectra of 90 bis-cyclometallated iridium complexes has been obtained using a simple combinatorial approach performed at room temperature. Trends in emission maxima are rationalized using Hammett parameters and invoking inter ligand energy transfer (ILET) processes. The screening approach allowed us to observe trends in the broadness of emission spectra opening the way for a rational approach to the engineering of the emission colour purity at a molecular level. Finally limitations to the screening strategy are discussed using a case study that involves two different monodentate ligands.

  通过在室温下使用简单的组合方法，我们获得了90种双环金属化铱复合物的发射光谱库。使用哈米特参数和配体间能量转移（ILET）过程，我们合理地解释了发射峰的最大值趋势。筛选方法使我们能够观察到发射光谱宽度的趋势，从而为在分子水平上合理设计发射颜色的纯度开辟了道路。最后，我们通过一个涉及两种不同单齿配体的案例研究讨论了筛选策略的局限性。

  The present invention relates to light emitting materials including a novel Ir complex, where the Ir is provided with a primary ligand selected from phenyl pyridine ligands substituted with at least one Cl atom. Such light emitting materials have been found to have a significantly enhanced photoluminescence quantum yield over other Ir complexes with a phenyl pyridine ligand having no Cl atom, or even over those with a phenyl pyridine ligand having a halogen atom other than Cl, such as a Br or F atom, and as a result specifically improve the efficiency of a light emitting device. The present invention further relates to the use of such light emitting materials and an organic light emitting device including such light emitting materials.

  本发明涉及包括一种新型Ir配合物的发光材料，其中Ir具有从取代有至少一个Cl原子的苯基吡啶配体中选择的主要配体。这些发光材料已被发现相对于没有Cl原子的苯基吡啶配体的其他Ir配合物，甚至相对于具有除Cl原子以外的卤素原子（如Br或F原子）的苯基吡啶配体的其他Ir配合物具有显着增强的光致发光量子产率，从而特别提高了发光器件的效率。本发明还涉及使用这种发光材料和包括这种发光材料的有机发光器件。

  A mild protocol for Ni-catalyzed trifluoromethylthiolation of aryl chlorides and bromides is described herein. The method utilizes AgSCF3 as an easily accessible nucleophilic trifluoromethylthiolating reagent and does not require any ligands or additives. Ortho-selectivity is achieved using a variety of directing groups such as imines, pyridines, and oxazolines for 24 examples in up to 95% yield.
