Synthesis of Novel Blue Light Emitting 9,9′-bianthracene Derivatives and Their Optoelectronic Properties

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.
