Novel fluorene-carzazole-based conjugated copolymers containing pyrazoline and benzothiazole segments for blue light-emitting materials
摘要:
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).
