A series of molecular weights and composition-tunable conjugated rod--rod block copolymers, poly(3-hexylthiophene)-b-poly(phenyl isocyanide) (P3HT-b-PPI), are synthesized in the presence of Ni(dppp)Cl2 as a single catalyst in one pot. Spherical aggregates and an amorphous state are observed in tetrahydrofuran and CHCl3 solutions, respectively. The atomic force microscopy reveals that the block copolymers can self-assemble into nanofibrils from CHCl3 on the substrate. The unique features warrant the resultant copolymers' potential study in organic photovoltaic and other electronic devices.
