Chiral ordered mesoporous silica has been synthesized by using a chiral surfactant (N‐
myristoyl‐L‐alanine sodium salt) as a template, 3‐aminopropyltriethoxysilane 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.
