以手性表面活性剂N-肉豆蔻酰-L-丙氨酸钠盐为模板剂，3-氨丙基-三乙氧基硅烷为共结构导向剂，正硅酸乙酯为无机源，合成了手性有序介孔氧化硅。介孔二氧化硅的螺旋度和形态由手性表面活性剂自组装过程中的搅拌速率决定（见图），为分子的手性自组装提供了新的见解。
Chiral ordered mesoporous silica has been synthesized by using a chiral surfactant (N-myristoyl-L-alanine sodium salt) as a template, 3-aminopropyl-triethoxysilane as a co-structure directing agent, and tetraethoxylsilane as an inorganic source. The helicity and the morphology of the mesoporous silica are determined by the stirring rate during the chiral surfactant self-assembly (see Figure), providing new insight into the chiral self-assembly of molecules.
