摘要
近年来,随着电子信息技术的快速发展与应用,相关新型技术与材料更新与发展的速度不断加快,有机发光二极管是近年来被广泛应用的新型平板显示技术,也是重点研究内容和方向,与以往荧光、磷光材料相比,热致延迟荧光材料具有显著的优势,器件中的量子效率理论可达100%。热延迟荧光材料属于有机小分子,其化学性质相对稳定,通常不需要与金属配位,使得其成本大幅度降低,所以,进一步开发与研究新型热致延迟荧光材料有着重要的意义。三嗪属于电子传输功能基团,其性能非常好,因具备很强的化学与光热稳定性,被广泛应用于有机光电子领域,以三嗪类化合物M1为主体材料,制备了相应的绿色与蓝色磷光期间,并深入探究了其电致发光性质,两者均有高效的性能,数据显示,M1可作为发光材料被广泛应用于有机电致发光器件当中,其主体材料性能也比较突出。
In recent years,with the rapid development and application of electronic information technology,the speed of updating and development of related new technologies and materials is accelerating.Organic light-emitting diodes are new flat-panel display technologies that have been widely used in recent years,and are also focused on research content and direction Compared with the previous fluorescent and phosphorescent materials,thermally delayed fluorescent materials have significant advantages,and the quantum efficiency theory in the device can be 100%larger.Thermally delayed fluorescent materials belong to small organic molecules.Their chemical properties are relatively stable.Usually,they do not need to coordinate with metals,which greatly reduces their cost.Therefore,it is of great significance to further develop and study new types of thermally delayed fluorescent materials.Triazine belongs to the electron transport functional group,and its performance is very good.Due to its strong chemical and photothermal stability,it is widely used in the field of organic optoelectronics,with triazine compound M1 as the host material,and prepared During the corresponding green and blue phosphorescence,and in-depth exploration of its electroluminescent properties,both have high-efficiency performance,the data shows that M1 can be widely used as a luminescent material in organic electroluminescent devices,its main material properties Also quite prominent.
