With the aim to obtain new phosphorescent Cu(I) compounds, several new 1,2-phenyl-bridged PN, PNP, and NPN chelate ligands were designed and synthesized. These ligands were found to form complexes with Cu(I) ion readily via either solution reactions or solid-state grinding process. The new Cu(I) compounds based on this class of ligands display phosphorescence with emission color ranging from blue to red. The structure of the ligand and the nature of the N-heterocycle in the chelate ligands were found to have a significant impact on the phosphorescent properties of the Cu(I) compounds.
为了获得新型磷光铜（I）化合物，设计并合成了几种新型的1,2-苯基桥连的PN、PNP和NPN螯合配体。发现这些配体通过溶液反应或固态研磨过程都能很容易地与铜（I）离子形成配合物。基于这类配体的新型铜（I）化合物呈现出磷光，发射颜色范围从蓝色到红色。发现配体的结构以及螯合配体中氮杂环的性质对铜（I）化合物的磷光性质有显著影响。
