中文摘要：

利用缩水甘油氧基丙基三甲氧基硅烷和甲基丙烯酸丙酯基三甲氧基硅烷对MCM-41进行改性,将稀土配合物Sm（HTH）3Phen（HTH=4,4,5,5,6,6,6-七氟-1-（2-噻吩基）-1,3-己二酮,phen=1,10-邻菲啰啉）组装到MCM-41及改性的MCM-41的孔道中,利用XRD,29Si核磁共振光谱,固体漫反射光谱等对其结构进行了表征,并研究组装体的发光性质.结果表明,相比纯配合物,Sm（HTH）3Phen在两种改性及未改性MCM-41中的发光纯度得到提高,组装体的激发光谱发生了蓝移.对比三种组装材料,对MCM-41表面进行改性可以有效地提高组装体的发光强度.

英文摘要：

The rare earth complex,Sm（HTH）3phen（HTH=4,4,5,5,6,6,6-heptafluoro-1-（2-thienyl）-1,3-hexanedione,phen=1,10-phenanthroline）,was incorporated into surface-modified mesoporous molecular sieve MCM-41 via reactions of the surface Si-OH with different silylation reagents such as 3-glycidoxypropyltrimethoxysilane and 3-（trimethoxysilyl）propylmethacrylate and their photophysical properties were studied.The results show that the surface silylation of MCM-41 provides a unique chemical environment for the incorporated rare earth complex.When the rare earth complex Sm（HTH）3phen was incorporated into the unmodified or modified MCM-41,the maximum wavelengths from excitation and emission spectra shifted toward shorter wavelengths.The emission intensity and color purity of the complex in these surface-silylated MCM-41s changed dramatically compared with the pure rare earth complex.
