Poly (vinylidene fluoride) (PVDF) exhibits piezoelectric characteristics, and It can be used as an synchronized piezoelectric-luminescence material through the formation of a complex with light emitting materials. However, there are only few research of composites or copolymers with polyfluorene-based polymers. Therefore, this study aims to synthesize a copolymer between polyfluorene-based polymers and PVDF. We synthesized Poly(dihydroxyl fluorene-co-dioctyl fluorene-co-benzothiadiazole) [P(F6OH-F8-BT)] via Suzuki coupling polycondensation. Macro chain transfer agent (Macro CTA) for polymerization of PVDF was synthesized by esterification of P(F6OH-F8-BT) and S-ethyoxythiocarbonyl mercaptoacetic acid (XAA). Finally, PVDF grafted copolymer [P(F6OH-F8-BT)-g-PVDF] was synthesized by radical addition fragmentation transfer (RAFT) polymerization. Synthesized polymers were characterized by several analytical methods and fabricated as a device to evaluate their properties.
