通过与茂金属羰基氯化物反应，纳米二氧化硅胺纳米颗粒（NPs， 12 nm SiO2核）被二茂铁（Fc）和五甲基二茂铁（Fc*）基团覆盖。循环伏安法在甲醇/乙腈中显示出具有扩散控制电流的完全化学和电化学可逆的单一波；用[FcCOMe][BF4]对Fc-SiO2和Fc*-SiO2 NPs进行比色滴定表明，氨基二氧化硅NPs的覆盖范围为335±50 Fc或240±40 Fc*基团。
Small aminosilica nanoparticles (NPs, 12 nm SiO2 core) were covered with ferrocenyl (Fc) and pentamethylferrocenyl (Fc*) groups by reactions with metallocenyl carbonyl chlorides. Cyclic voltammetry in methanol/acetonitrile showed a single fully chemically- and electrochemically-reversible wave with a diffusion-controlled current; colorimetric titrations with [FcCOMe][BF4] of the Fc-SiO2 and Fc*-SiO2 NPs indicated a coverage of the aminosilica NPs of 335 ± 50 Fc or 240 ± 40 Fc* groups.
