摘　　要：有机电致发光二极管(Organic Light Emitting Diode,OLED)因其自发光、低驱动电压、广色域、面发光及柔性可弯曲等优势,在新型显示和固态照明领域引起了广泛关注和密切研究。在高性能的OLED研发中,作为三基色之一的蓝光发光材料及其器件相对滞后,阻碍了OLED产业化进程。9,9′-联蒽作为一种新兴的蓝色荧光材料,近年来备受关注。本文综述了9,9′-联蒽类蓝光材料在OLED中的应用进展,深入探讨9,9′-联蒽类蓝光材料对OLED性能提升的贡献,通过对其分子结构特性分析发现异构化、氟取代、非对称结构及空间位阻效应等分子设计策略在提高蓝光OLED效率和稳定性方面起到了关键作用。此外,本文进一步探讨了未来OLED发展方向,包括新型分子结构的开发、发光机理的深化理解、柔性可弯曲及大尺寸OLED应用技术的创新,旨在为高性能OLED蓝光材料的研究及产业化提供指导和借鉴。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 highperformance 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.
