摘 要:制备了一种齐聚苯撑乙烯(OPPV)/MCM-41复合材料.氮气吸附等温线结果证明了OPPV被成功包覆在MCM-41中.紫外-可见光谱结果表明,OPPV以近乎单分散的状态分布在MCM-41孔道中.荧光光谱结果表明,与OPPV相比,OPPV/MCM-41复合材料具有更强的光稳定性和更高的发光效率.Preparation of an oligo (p-phenylkene vinylene) (OPPV) inside the channels of the mesoporous silica MCM-41 was described. Presence of OPPV was observed by N2 adsorption istherms. Fluorescence spectra results show that the luminescent peak of the OPPV in the composites undergo a blue shift about 80 nm and its emission intensity is enhanced compared with that of OPPV in solid state, and the photostability is much better, all of which make such composites of more practical significance.
