説明

9,9-Dialkyl oligofluorenes end-functionalized with styryl group such as oligo (9,9-dimethylfluorene) (PF(C1)-St) and oligo (9,9-didodecylfluorene) (PF(C12)-St) were successfully prepared by a Suzuki coupling reaction of (7-bromo-9,9-dimethylfluorene-2-yl) boronic acid and (7-bromo-9,9-didodecylfluorene-2-yl) boronic acid followed by end-capping reaction with 4-bromostyrene, respectively. The resulting oligomers were applied for a radical copolymerization with styrene to synthesize the polystyrenes bearing with oligofluorene graft chains (PF(Cx)-g-PS, x = 1, 12). Fluorescence spectrum of the PF(C1)-g-PS film showed an increase of 0→0 transition and a blue shift in comparison with original PF(C1)-St, suggesting the relaxation of intermolecular interaction between oligofluorene units. In addition, phase transition from the β-phase to the α-phase was observed for PF(C12)-g-PS, indicating the effects of long alkyl chains.
