炔双膦配体和二亚胺类配体混配的一价铜双核配合物的合成与表征

Synthesis and characterization of monovalent copper binuclear complexes mixed with acetylene bisphosphine ligands and diimide ligands

以炔双膦配体和二亚胺类配体为共配体,与四乙腈一价铜盐反应,最终合成了4种新颖的一价铜双核配合物,产率为35%～50%.进一步对其中2种配合物的晶体学结构进行表征,并测试了配合物的紫外吸收光谱和固体发光性能.这4种铜配合物均具有固体发光现象,其中配合物4c的发光性能最好,是一种潜在的固体发光材料.

Four kinds of monovalent copper binuclear complex were synthesized using diimide ligands and acetylene bisphosphine ligands as co-ligands and reacting with tetraacetonitrile monovalent copper.The yield ranged from 35%to 50%.Furthermore,the crystal structures of two kinds of complexes were characterized,and the ultraviolet absorption spectrum and luminescence performance of solids were examined.The results showed that all the four kinds of complex had the phenomenon of solid emission,and the complex 4c had the best emission ability,which means it has potential applica-tions in luminescent materials.
