摘　　要：通过对介孔SBA-15孔壁氨基化(SBA-15-NH2),然后与C60反应形成化学键,成功地将C60组装进入SBA-15孔道中,合成了C60/SBA-15介孔复合材料.通过X射线衍射(XRD)、红外光谱(FTIR)、紫外-可见光谱(UV-V is)和差热-热重分析(TG-DTA)等方法对其进行了表征.同时,对复合材料的荧光性质进行了研究.结果发现,SBA-15-NH2在575 nm处出现发射峰,C60/SBA-15介孔复合材料在554 nm处出现发射峰,峰位蓝移21 nm.The hybrid materials C60/SBA-15-NH2 were synthesized by modifying the channel surface with amino-functional group. These materials were characterized by XRD, FTIR, UV-Vis and TG/DGA analysis. Furthermore, the fluorescence（FL） spectra of C60 in mesoporous materials were investigated. The FL emission of C60/SBA-15-NH2 was observed at 554 nm, which is different from that of SBA-15-NH2 at 575 nm. The emission band has blue-shifted 21 nm.
