8-羟基喹啉衍生物金属配合物的发光研究

Synthesis and Photoluminescent Properties of Three Complexes of 8-hydroxy Quinoline Derivative with Zn^(2+),Cu^(2+) and Cd^(2+)

通过Claisen重排反应合成了7-烯丙基-8-羟基喹啉配体,并且合成了金属离子Zn^(2+)、Cu^(2+)和Cd^(2+)的配合物。研究了配体及金属配合物的紫外吸收光谱、红外光谱以及光致发光现象。结果表明,配体与金属离子之间形成了稳定配合物,在紫外光激发下,Zn-配合物和Cd-配合物分别发出黄光和蓝-绿光,而Cu-配合物表现为配体的发光。

Three new metal complexes of 7- allyl- 8- hydroxyquinoline with Zn-（2＋）,Cu-（2＋）and Cd-（2＋）were prepared and characterized,and 7- allyl- 8- hydroxyquinoline was synthesized by the Claisen rearrangement. The UV- Vis,IR and photoluminescence spectra of the complexes were investigated. The results showed that the metal ions were coordinated by the oxygen atom of the hydroxyl group and nitrogen atom of the quinoline ring to form stable metal complexes,and the Zn（ Ⅱ） complex and Cd（ Ⅱ） complex exhibited yellow and blue- green emissions under ultraviolet light excitation,respectively. For Cu（ Ⅱ） complex,the blue emission came from the ligand.
