A series of novel fluorene-carbazole-based copolymers with pyrazoline and benzothiazole units were synthesized successfully through Suzuki coupling reactions.The molecular structures and thermal properties of these polymers were characterized by FT-IR, ~1H NMR,DSC and TGA.GPC results indicated that the weight-average molecular weight(M_w) and polydispersity of these polymers were in range(12,000-14,000)and(1.8-2.0),respectively.The two resulting polymers have high photoluminescence quantum efficiency implying that they may be promising candidates for polymer light-emitting diodes (PLEDs).
