通过引入不同的取代基，采用Suzuki偶联反应，合成了一系列9,9′-联蒽衍生物新型蓝光材料，并研究了它们的紫外-可见吸收、荧光发射、荧光量子效率和电化学等性能。研究结果表明，这些化合物在二氯甲烷中均发射蓝色荧光，与9,9′-联蒽相比，其荧光发射峰均红移了7 nm，达到453 nm，是典型的蓝色荧光，同时也具有较高的荧光量子效率。

A series of novel blue light emitting materials 9,9′-bianthracene derivatives have been designed and synthesized by introducing different substituent groups through Suzuki coupling reactions. Their structure was identified by 1H NMR and UV-Vis absorption and fluorescence emission. Moreover, their fluorescence quantum efficiency and electrochemical properties were characterized in detail. The results indicate that all these compounds emit blue light, compared with 9,9′-bianthracene, the maximum emission peak of these materials is at 453 nm, red shift of 7 nm, and it is the typical blue fluorescence. This is because these derivatives have a non planar geometric structure. These derivatives also present high fluorescence quantum efficiency and are 1.18～1.43 times than 9,9′-bianthracene. In addition, their redox actives are also improved. Consequently, it was believed that these derivatives are potential ideal blue light fluorescent materials.
