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 from lamellar to cylindrical and then to spherical,doi:10.1039/c0sm01385d fatcat:myluusn3obai7b43sspifn5elu
