This is the first study that elucidates the effect of alcohol alkyl chain length on the formation of mesoporous silica ( m SiO 2 ) layers on cetyltrimethylammonium bromide (CTAB)‐stabilized gold nanorods (CGNRs). The growth tendencies of the m SiO 2 layers on the CGNRs (CGNR@ m SiO 2 ) in various alcohol solvents differed quite substantially from those observed for previously reported spherical silica particles. The formation of the m SiO 2 layer was closely related to the interaction between the CTAB bilayer and alcohol.
