摘要 通过Ullmann偶联、Suzuki偶联等反应合成了三种咔唑或二苯胺封端的芴类有机小分子CPhF、CPh_2F和DAF,并通过核磁共振谱~1H NMR和^(13)C NMR对其进行了表征。化合物CPhF和CPh_2F的CH_2Cl_2稀溶液的最大吸收峰位于345nm,发射峰分别位于393和405nm,属于蓝紫色荧光;化合物DAF的CH_2Cl_2稀溶液的最大吸收峰位于364nm,发射峰位于428nm,属于蓝色荧光;化合物CPhF和CPh_2F的玻璃化温度分别为97和111℃,分解温度分别为368和416℃,均具有良好的热稳定性。 Three fluorene derivatives end-capped by carbazole or diphenylamine were synthesized through Ullmann coupling and Su -zuki coupling reactions,and their structures were characterized by 1 H NMR and 13 C NMR.The maximum absorption wavelengths and emission wavelengths of CPhF ,CPh2 F and DAF in dilute CH2 Cl2 were λabs=345,345,364nm,and λem=393,405,428nm,re-spectively.CPhF and CPh2 F had good thermal stability,for their glass transition temperatures were 97 and 111℃and decomposition temperatures were 368 and 416℃,respectively.
