Dissipative particle dynamics simulations were performed on the morphology and structure of multicompartment micelles formed from π‐shaped ABC block copolymers in water. The influences of chain architectures were studied in a systematic way, and a rich variety of morphologies were observed, such as spherical, wormlike, X‐shaped, Y‐shaped, ribbon‐like, layered rod‐like, layered disk‐like, as well as network morphologies. The simulations show that the distance between the two grafts plays an important role in control of the morphology. Since π‐shaped ABC block copolymers can be reduced to linear ABC and star ABC block copolymers, they are good model copolymers for studying the self‐assembly of complex block copolymers into micelles. The knowledge obtained in this work as well as the new morphologies identified provide useful information for future rational design and synthesis of novel multicompartment micelles.
