Robust self‐assembly with very high order is demonstrated by polyisobutylene‐ block ‐poly(ethylene oxide) (PIB–PEO) copolymers tailor‐made by combining living cationic and anionic polymerization. A cubic micellar phase with long‐range order and a glassy phase consisting of deformed spheroids are identified. Application of PIB–PEO in the synthesis of porous titanium oxide yields perfect anatase crystalline films with high regularity (see Figure).
