新型偶氮苯金属配合物的合成与性能

Synthesis,Characterization and Properties of Novel Azobenzene Containing Metal Complexes

合成了新型偶氮苯金属配合物。分别采用光谱分析、热分析及X射线衍射测试技术对产物进行了表征和测试。结果表明,连接偶氮苯和金属配合物之间碳链的长度对该化合物的相转变和荧光特性具有特殊的影响。该系列化合物在紫外光和热作用下具有99%以上的偶氮苯顺-反异构化反应效率;具有290和560 nm这2个波段的荧光发射光谱。由其中1个金属配合物分散在聚甲基丙烯酸甲酯网络而形成的介质可作为全息信息存储材料而实现全息图像的写入和读出。

The azobenzene-containing metal complexes with different length carbon chains have ben synthesized.The compounds have been characterized by spectrophotometric methods as well as thermal,and X-ray diffractometric analysis.It is found that the carbon chain length between azobenzene moiety and diamine metal complex has a great influence on the thermal and fluorescent behavior of the bi-functional compounds.The advantage of combining azobenzene chromophore with metal complex is evidenced by the remarkable high efficiency of azobenzene isomerization behavior and two fluorescent emission bands centered at 290 and 560 nm respectively,induced by metal complex part of the compounds.The holographic image inscription and readout experiment by one of the metal complexes in PMMA matrices is successful.
