We report the synthesis and the self-assembled morphologies of a series of new rod-coil diblock copolymers, poly [2, 7-(9, 9-dihexylfluorene)]-b-poly (4-vinylpyridine)(PF-b-P4VP). The rod-coil diblock copolymers were synthesized via Suzuki coupling reaction and living anionic polymerization. Probing by transmission electron microscopy, small-angle X-ray scattering and atomic force microscopy, we found that the microphase separation varies ...
