With the aim to obtain new phosphorescent Cu(I) compounds, several new 1,2-phenyl-bridged P∧N, P∧N∧P, and N∧P∧N 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
其目的,以获得新的磷光的Cu(I)的化合物,许多新的1,2-二苯基桥接的P ∧ N,P ∧ Ñ ∧ P,和N ∧ P ∧设计并合成Ñ螯合配体。发现这些配体容易通过溶液反应或固态研磨过程与Cu(I)离子形成络合物。基于这类配体的新的Cu(I)化合物显示磷光,发射颜色范围从蓝色到红色。发现配位体的结构和螯合配位体中的N-杂环的性质对Cu(I)化合物的磷光性质具有重大影响。

A novel PNP bis(secondary phosphine)pyridine pincer ligand, 2,6-bis(2-(phenylphosphino)phenyl)pyridine, has been prepared in high yield, and the properties of the doubly deprotonated form as a ligand in K4(PNP)2(THF)6 and (PNP)Zr(NMe2)2 have been investigated. The neutral PNP ligand has been isolated as a mixture of noninterconverting diastereomers, due to the presence of two chirogenic phosphorus
