A trans-N-heterocyclic carbene (NHC) platinum(II) acetylide complex bearing phenyl acetylene ligands (NPtPE1) has been synthesized via the Hagihara reaction in 64% yield. The complex features spectrally narrow deep blue emission with a phosphorescence quantum yield (0.30) and lifetime (∼10 μs) in the solid state. The modest quantum yield and lifetime make NPtPE1 a candidate for incorporation into an organic light emitting diode (OLED). Prototype devices exhibited a maximum EQE of 8% with CIE (0.20,0.20). To the best of our knowledge, this is the first example of a platinum(II) acetylide bearing NHC ligands to be incorporated into an OLED.

寻找更深的蓝调：反式-N-杂环碳白金苯乙炔化物作为磷光OLED的掺杂剂

通过Ha原反应，以64％的产率合成了带有苯基乙炔配体（NPtPE1）的反式-N-杂环卡宾（NHC）铂（II）乙炔化物络合物。该配合物具有光谱窄的深蓝色发射，在固态下具有磷光量子产率（0.30）和寿命（〜10μs）。适中的量子产率和寿命使NPtPE1成为掺入有机发光二极管（OLED）的候选材料。原型设备在CIE（0.20,0.20）下的最大EQE为8％。据我们所知，这是第一个带有NHC配体的乙二酸铂（II）掺入OLED的例子。
