Self‐assembly behaviors of rod–coil–rod triblock copolymers in the selective solvent are systematically investigated by dissipative particle dynamic simulations. Three selective solvents are considered: the pure coil‐selective solvent, the pure rod‐selective solvent, and the mixed solvent. The concentration‐induced morphologies and morphological transition affected by the rod and coil length are examined. The micelle adopts the overall shape of sphere, nematic bundle, worm, cylinder, lamella, coil‐, and rod‐aggregated hollow cylinders, and network. In the coil‐selective solvent, increasing coil length can defer the phase transition from sphere to other morphologies while increasing rod length can advance the transition. In the rod‐selective solvent, an opposite influence rule is found.
