9,9'-Bianthracene-Based Blue Fluorescent Emitters for High-Performance Organic Light-Emitting Diodes
Organic light emitting diodes (OLEDs) have attracted extensive attention and research interest in advanced display and solid-state lighting due to their self-luminescence, low drive voltage, wide color gamut, surface luminescence, flexibility and rapid response. One of the primary colors of OLED, the development of blue emitter is still lagging far behind. Interestingly, 9,9'-bianthracene as a promising blue-emitter for high-performance fluorescent OLEDs exhibits excellent optoelectronic performance in recent years. Here, we review the progress with the development of 9,9'-anthracene-based blue fluorescent materials and gain insight into their contribution towards enhanced OLED performance. Different approaches to achieve blue emission from molecular design including isomerization, fluorine substitution, asymmetrical structuring, and steric hindrance effects are discussed, with particular focus on device efficiency and stability. Furthermore, an outlook for future challenges and opportunities of OLEDs from the development of new molecular structures, understanding of luminescence mechanisms as well as innovation in flexible and large-scale panels is provided.
