Eight iridium complexes by employing 3-methyl-6-(naphthalen-2-yl)-imidazo [2,1-b] thiazole (mn2mt) and 3-methyl-6-(naphthalene-1-yl)imidazo [2,1-b] thiazole (mn1mt) as the primary ligands, as well as picolinic acid (pic), isoquinoline-3-carboxylic acid (3-IQA), quinoline-2-carboxylic acid (2-QA), and 2-(pyridin-2-yl)phenol (hppy) as the auxiliary ligands, were synthesized for applications where organic optical function materials are required. On top of that, their structures, photoluminescence, and electrochemical properties were thoroughly investigated. More specifically, their maximum emission wavelengths can be detected in the range of 557-609 nm, while the luminous colors span from the green to the standard red region. Interestingly, by employing the synthesized Ir^III complexes as emitters, light-emitting diode (LED) chips based on InGaN chip excitation were fabricated, which divulged good performances.

使用 3-methyl-6-(naphthalen-2-yl)-imidazo [2,1-b] thiazole (mn2mt) 和 3-methyl-6-(naphthalene-1-yl)imidazo [2,1] 形成八种铱络合物-b] 噻唑 (mn1mt) 作为主要配体，以及吡啶甲酸 (pic)、异喹啉-3-羧酸 (3-IQA)、喹啉-2-羧酸 (2-QA) 和 2-(吡啶) -2-基）苯酚（hppy）作为辅助配体，合成用于需要有机光学功能材料的应用。最重要的是，对它们的结构、光致发光和电化学性质进行了彻底研究。更具体地说，它们的最大发射波长可以在 557-609 nm 范围内被检测到，而发光颜色从绿色到标准红色区域。有趣的是，通过使用合成的 Ir ^III以InGaN芯片为激发源的复合物作为发射体，制备了发光二极管（LED）芯片，表现出良好的性能。
