合成了一种新型的T_h-对称的富勒烯六加成衍生物HDTC_60.该化合物具有12条长链,内部是亲水的三甘醇基团,外部是正癸基链,是一种反相类胶束分子.利用该种六加成衍生物为模板以及微反应器制备了HDTC_60-Ag复合纳米体系,并用紫外-可见吸收光谱、透射电子显微镜等手段进行了表征.结果表明,HDTC_60-Ag复合纳米体系具有典型的银纳米粒子的表面等离子共振吸收峰,此纳米体系中的银纳米颗粒粒度均匀,大小约为4.7nm.光限幅实验研究表明,HDTC_60-Ag复合纳米体系的形成可极大改善富勒烯衍生物本身的光限幅性质.
A new type of T_h-symmetrical fullerene hexaadduct derivative HDTC_60 has been synthesized. The compound has 12 long chains, the internal is a hydrophilic triethylene glycol group, the external is n-decyl chain, an anti-phase HDAC_60-Ag nanocomposites were prepared by using the hexaadduct derivatives as templates and microreactors and characterized by UV-Vis absorption spectra and transmission electron microscopy.The results showed that HDTC_60-Ag The composite nanostructures have the typical surface plasmon resonance absorption peaks of silver nanoparticles, the size of the silver nanoparticles in the nanostructures is about 4.7 nm, and the optical limiting experiments show that the formation of HDTC-60-Ag nanocomposites can be extremely polar Greatly improve the optical limiting properties of fullerene derivatives themselves.
