Three pargyline-phosphine copper(I) clusters, Cu(CC-CHN)(PPh) (1) and Cu(CC-CHN)(dppy) (dppy = diphenyl-2-pyridylphosphine; X = PF for 2 and X = ClO for 3), were synthesized. Their structures were fully characterized using various spectroscopic methods and X-ray crystallography, which showed that the stoichiometry and nature of pargyline and phosphine ligands play an important role in tuning the structure and photophysical features of Cu(I) clusters. Interestingly, clusters 1, 2 and 3 exhibited red, orange and yellow phosphorescence with high quantum yields of 88.5%, 22.0% and 40.2%, respectively, at room temperature. Moreover, clusters 1-3 show distinct temperature-dependent emissions. The excellent luminescence performance of 1 and 3 was designed and employed for the construction of monochrome and white light-emitting devices (LEDs).
合成了三种巴吉林 - 膦铜（I）簇合物，即Cu(C≡C - CHN)(PPh)（1）和Cu(C≡C - CHN)(dppy)（dppy = 二苯基 - 2 - 吡啶基膦；对于2，X = PF，对于3，X = ClO）。使用各种光谱方法和X射线晶体学对它们的结构进行了全面表征，结果表明巴吉林和膦配体的化学计量和性质在调节Cu（I）簇合物的结构和光物理特性方面起着重要作用。有趣的是，簇合物1、2和3在室温下分别呈现出红色、橙色和黄色磷光，量子产率分别高达88.5%、22.0%和40.2%。此外，簇合物1 - 3表现出明显的温度依赖性发射。1和3优异的发光性能被设计并用于构建单色和白色发光器件（LED）。
