Amphiphilic block copolymer templating strategies are extensively used for syntheses of mesoporous materials. However, monodisperse tubular nanostructures are limited. Here, a general method is developed to synthesize monodisperse nanotubes with narrow diameter distribution induced by self‐assembly of block copolymer. 3‐Aminophenol (AP) and formaldehyde (F) polymerize and self‐assemble with cylindrical PS‐b‐PEO micelles into worm‐like PS‐b‐PEO@APF composites with uniform diameter (49 ± 3 nm). After template extraction, worm‐like APF polymer nanotubes are formed. The structure and morphology of the polymer nanotubes can be tuned by regulating the synthesis conditions. Furthermore, PS‐b‐PEO@APF composites are uniformly converted to isomorphic carbon nanotubes with large surface area of 662 m 2 g −1 , abundant hierarchical porous frameworks and nitrogen doping. The synthesis can be extended to silica nanotubes. These findings open an avenue to the design of porous materials with controlled structural framework, composition, and properties for a wide range of applications.
