Rod-Coil block copolymers composed of poly(9,9-dihexylfluorene) (PF, Rod), polystyrene (PS, Coil) were synthesized by a combination of Suzuki coupling polymerization and an atom transfer radical polymerization. Fluorescence property of the resulting block copolymers were studied in the mixed solvent to investigate the aggregation state epending on the segment ratios. Maximum luorescence wavelength of the resulting block copolymers were observed to exhibit blue shift by increasing the selective solvent, suggesting the formation of H-aggregate in PF segment.Key Words : polyfluorene, rod-coil block copolymer, Suzuki coupling polymerization, atom transfer radical polymerization, fluorescence property.
