چکیده انگلیسی
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 (Mw) 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).
