摘要
将稀土铕配合物—Eu(BA)3(TPPO)2分别组装到未修饰和修饰的介孔分子筛(SBA-15)中,详细地表征了样品的形貌和结构,系统地研究了其光致发光性质和稳定性,并与纯的稀土配合物进行比较研究。研究结果表明,SBA-15为组装的稀土配合物提供了良好的刚性环境,组装后的稀土铕离子配合物的光致发光稳定性比纯的配合物的光致发光稳定性有很大的提高。这将使稀土配合物在分子光学、电子器件等诸多领域具有重要的应用前景。
The complexes(Eu(BA)a (TPPO)2)were assembled in un-modified and modified SBA-15, re- spectively. The morphologies and structure were characterized. The photolumineseence properties and stability were systematically studied in contrast to the pure complexes. The results indicate that the SBA-15 provide fine rigid environment for the rare earth complexes. In comparison to the pure complex, the photostability of the assembled samples improved considerably.
