对高效且光稳定的镧系元素发光材料的需求急剧增加，特别是关于它们在照明设备和生物科学中的日益增长的应用。为此，我们已经开发了一种简便的合成苯并咪唑取代的吡啶-2-羧酸，有效地敏化铕发光的均配中性九配位配合物的总量子产率为56-61%，在室温条件下的固态寿命为2.1-2.6 ms。本文报道的配合物是设计各种发光材料的潜在的催化剂。
The need for efficient and photostable lanthanide luminescent materials is dramatically increasing, in particular with respect to their growing application in lighting devices and biosciences. To this end, we have developed a facile synthesis of benzimidazole-substituted pyridine-2-carboxylic acids that efficiently sensitize europium luminescence in homoleptic neutral nine-coordinate complexes with overall quantum yields of 56-61% and lifetimes of 2.1-2.6 ms in the solid state at ambient conditions. The complexes reported here are potential synthons for the design of a variety of luminescent materials.
