Dissipative particle dynamics simulation is performed to study the sensitive influence of the molecular architecture and/or segment sequence on the morphology diversity of the multicompartment micelles. The multicompartment micelle morphologies formed by ABC triblock copolymers with various molecular architectures, such as the linear, the pentalinear, the cyclic, the star-like, the tetra-arm, and the pi-shape are investigated, and different morphologies of the multicompartment micelles, for example, worm-like, hamburger, sheet-like with pores, sweet potato with alternating layers, sheet-like with cylinder-inclusion, and three-dimensional network are observed in this work. The density profiles and the radial distribution functions are calculated to characterize the structures of the multicompartment micelles. The preparation of complex multicompartment micelles can be fulfilled by simply changing the segment sequence and molecular architecture such as adding new bonds and grafting points.
