The micrometer-scale self-assembly behaviour of MCM-41-type mesostructured silica is revealed through the study of a family of vesicular mesostructured silica with topology genus from 1 to 0 (see Figure and inside cover). The topological transformation and assembly kinetics demonstrate that the formation of the vesicular structure is closely correlated with the properties of the cetyltrimethylammonium–silicate building block and the hydrophobic nature of the ester additive.
