摘要
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.
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.
