tetranuclear copper complexes have been synthesized in good yields using a modular ligand system based on triazole-phosphines. This kind of ligand is easily accessible through an improved one-pot synthesis that permits the facile introduction of various alkyl or aromatic substituents at the 1-, 4-, or 5-position of the triazole ring. X-ray crystallography revealed three different types of complexes: neutral di-
使用基于三唑膦的模块化配体系统,已经以高收率合成了许多新颖的发光二,三和四核铜配合物。这种配体可通过改进的一锅合成法轻松获得,该方法可在三唑环的1、4或5位上轻松引入各种烷基或芳族取代基。X射线晶体学揭示了三种不同类型的配合物:具有C i对称性的中性双核和四核结构,以及带电C 3的带电三核结构对称。光谱评估表明,就其在有机发光器件中的潜在用途而言,其光致发光性能令人鼓舞,最大值在500-550 nm范围内,这取决于用于络合的三唑配体的取代方式。实验观察得到基态和激发态的密度泛函理论计算的补充。
