摘要
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.
