Abstract
本发明涉及“含氮杂环衍生物和使用该衍生物的有机发光二极管器件”属于有机电子发光材料领域。如式(I)所示的有机化合物,将蒽以及蒽的衍生物通过萘基与菲啰啉偶联,得到高性能的材料。本发明制备得到了具有高三线态能量的电子材料,并使用所述的电子材料作为有机发光二极管的发光层的电子传输材料,由此促进了发光层中的能量转移,并改进了有机发光层的蓝色发射效率和使用寿命,同时启动电压降低。
Description
技术领域
本发明涉及一种含氮芳香杂环衍生物和一种有机发光二极管(OLED)器件,更具体而言,涉及一种因高三线态能量和电子传输性能而具有较高的发光效率的含氮芳香杂环衍生物和一种使用该含氮芳香杂环衍生物的OLED器件。
背景技术
近几年来,对有机电致发光器件进行了广泛研究和开发。在这种发光元件的基本结构中,含发光物质的层插在一对电极之间,通过施加电压到该元件上,可获得来自发光物质的光发射。
由于这种发光元件是自发光元件,因此它们相对于液晶显示器在高像素可见性和省去对背光需求的方面具有很大的优势,由此被视为适合于平板显示元件。发光元件同样具有非常大的优势的,因为它们是薄且轻的,非常快速的应答是这种元件的特征之一。
此外,由于可以以薄膜形式形成这种发光元件,因此可以提供平面光发射。因此,可容易地形成具有大面积的元件。这是采用以白炽灯和LED为代表的点光源或以荧光灯为代表的线性光源难以获得的特征。因此,发光元件作为可应用于照明的平面光源等来说还具有大的潜力。
通过有机化合物形成的激发态可以是单线态或三线态。来自单线态激发态(S*)的发射是荧光,而来自三线态激发态(T*)的发射被称为磷光。另外,认为发光元件内其统计生成比为S*:T*=1:3。在将单线态激发态的能量转变为光发射的化合物中,在室温下没有观察到来自三线态激发态的发射,而仅仅观察到来自单线态激发态的发射。因此,认为使用荧光化合物的发光元件的内量子效率具有25%的理论极限,基于为1:3的S*与T*之比。因此有机电致磷光材料是近来受人瞩目的一类材料,具有高的发光效率和发光亮度的有机电致发光材料,它通过引入重金属原子的方法,利用了室温下原本禁阻的三重态跃迁,从而使内部量子效率理论能够达到100%,是单一荧光材料的4倍(1、Cao Y.,Parker I.D.,Heeger J.,Nature,1999,397:414-417.2、Wohlgenann M.,et al.Nature,2001,409:494-497.)。有机电致磷光材料常用的重金属原子多为过渡金属,其中以铱的应用最广、研究最为详细,这是因为金属铱配合物具有高的效率、室温下较强的磷光发射以及可以通过配体结构的调整而调节发光波长使电致发光器件的颜色覆盖整个可见光区。因此设计研究合成新型高效的金属铱配合物,对开发磷光材料具有重大意义。
但是,掺杂剂的效率因猝灭现象剧烈降低,因而对于不具有主体的掺杂剂的发光层存在限制。因此,期望的是,通过掺杂剂和具有更高热稳定性和三线态能量的主体来形成发光材料层。
在包含磷光化合物的OLED器件中,来自阳极的空穴和来自阴极的电子在发光材料层的主体处结合。发生主体的单线态激子向掺杂剂的单线态或三线态能级的能级跃迁,并发生来自主体的三线态激子向掺杂剂的三线态能级的能级跃迁。跃迁至掺杂剂的单线态能级的激子再次跃迁至掺杂剂的三线态能级。掺杂剂的三线态能级的激子跃迁至基态,使发光层发光。
目前作为电子传输和注入的材料比较少,磷光器件不仅满足电子传输速度快,还要使三线态的能级高,把磷光器件产生的激发子限制在发光层,因此开发高三线态和电子传输速度快的材料是很重要的。菲啰啉衍生物具有低的HOMO、LUMO,可以有效传输电子和阻挡空穴,电子迁移率可以到10-4,但是菲啰啉容易出现结晶,以及长时间使用,发生晶体的转化,严重影响到器件的寿命;因此对菲啰啉必须进行结构的调整,避免发生结晶现象,得到无定型的材料。
菲啰啉具有大的平面结构,有利于电子的迁移,4,7-二苯基-1,10-菲啰啉(Bphen)和4,7-二苯基-2,9-二甲基-1,10-菲啰啉(BCP)电子迁移率可以达到10-4,三线态3.0ev左右,可以满足目前磷光材料的要求。但是这两个材料因为容易结晶,寿命难以达到工业应用要求,因此使用受到了限制。因为菲啰啉高的电子迁移率和三线态,目前已经被引入了不同结构,得到不同性能的材料。得到的材料电子迁移率仍然能够保持菲啰啉的迁移率,因为是通过苯基键连,三线态只有2.5ev,只能作为红光材料的电子传输材料使用(出光专利TW201329195中的A、B化合物)。
上述化合物采用苯键连方式,虽然能够改善材料的性能,但是降低了材料的三线态(2.5ev),只能作为红色磷光材料的电子传输材料,无法应用到绿光、蓝光磷光器件。
发明内容
本发明涉及一种含氮杂环衍生物和一种使用该含氮化合物的OLED器件,两者基本解决了因现有技术的限制和缺陷所导致的一个或多个问题。
本发明的一个目的是提供一种电子传输材料化合物,所述的电子传输材料具有高的三线态能量和高的电子传输性能。
本发明的另一个目的是提供一种具有提高的发光效率的OLED,其使用寿命长,启动电压低。
