• fluorene-carbazole copolymers
• pyrazoline
• bezothiazole

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, H-1 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).
