以三嵌段化合物P123为模板剂、正硅酸乙酯(TEOS)为无机硅源合成了有序介孔分子筛SBA-15. 选择Tb(DBM)3phen为客体, 纳米级介孔分子筛为主体, 在氯仿中进行分子组装, 制备具有强发光性能的超分子纳米复合材料Tb(DBM)3phen/APTES-SBA-15. 采用XRD, HRTEM, N2吸附/脱附, FTIR和荧光光谱分析等对复合材料的结构与性能进行了研究.

关键词: Tb(DBM)3phen, SBA-15, 复合, 光致发光

Nanosized mesoporous molecular sieve SBA-15 was synthesized with tetraethyl orthosilicate (TEOS) as the source of silica and P123 [Poly(ethylene glycol)20-Poly(propylene glycol)20-Poly(ethylene glycol)20] as the template. The photoluminescent functional supramolecule Tb(DBM)3phen/APTES-SBA-15 between the nanosized SBA-15 and Tb(DBM)3phen was prepared in chloroform, and characterized by XRD, HRTEM, N2 absorption/desorption, IR and fluorescent spectroscopy.

Key words: Tb(DBM)3phen, SBA-15, composite, photoluminescent
