摘　　要：以咔唑为原料,分别通过溴代和C-N耦合反应,对咔唑的3,9位进行衍生,合成了3-溴-9-(2-苄溴基)咔唑,再与不同的芳基硼酸进行Suzuki反应制备目标化合物。通过核磁和元素分析对其进行表征。通过热重分析(TGA)法对磷光主体材料的热力学性能进行研究,通过紫外-可见吸收和低温磷光光谱对材料的光学性能进行研究。结果表明:主体材料具有较高的热分解温度和三线态能级。A series of novel carbazole-based derivatives were synthesized by using 3-bromo-9-(2-bromobenzyl)-carbazole which was synthesized using carbazole via bromination and C-N coupling reactions,reacting with corresponding arylboronic acid.The compounds obtained were characterized by elemental analysis,1 H NMR,and 13 C NMR spectroscopy.The thermal properties of these materials were studied by thermogravimetric analysis.The photophysical properties were also investigated by UV-vis and phosphorescent spectrums.The results showed that all host materials possessed high decomposition temperature and triplet energy levels.
