Abstract
A series of highly efficient ultraviolet (UV) organic light-emitting devices (OLED) based on bi(9,9-diarylfluorene)s was analyzed. The bi(9,9-diarylfluorene)s were conveniently synthesized with reasonable isolated yields by Pd-catalyzed Suzuki coupling reactions of 2-bromo-9,9-diarylfluorenes and the corresponding 9,9-diarylfluorene-2-boronic esters. Different aryl substituents were introduced to investigate the structure-property relationship. The results show that these intriguing materials demonstrate the first example of pure aromatic hydrocarbons as highly potential UV emitters in OLED applications.
