Description
技术领域
本发明涉及有机发光器件技术领域,更具体的说是涉及一种发光辅助材料及其制备方法和在制备有机电致发光器件中的应用。
背景技术
近年来,有机发光二极管(OLED:Organic Light Emitting Diode)作为一种新型和有前途的显示技术逐渐进入人们的视野。OLED是一种由多层有机薄膜结构形成的电致发光器件,其中的有机薄膜是利用蒸镀、沉积或旋涂工艺在基板上形成的有机发光材料的膜。
有机电致发光装置(有机EL装置)是一种自发光装置,利用有机物质将电能转换为光能的现象。其具有的优势在于提供了更宽的视角、更高的对比率以及更快的响应时间。目前,便携式显示屏市场为了满足大面积显示屏的需求而呈现出其大小不断增加的趋势,因此,所消耗的电力也高于现有便携式显示屏的消耗电力。在这种情况下,对于仅配备了电池这一有限电力供应源的便携式显示屏,电力消耗是一种非常重要的性能因素,也必须解决其效率和寿命问题。
为了提高有机电致发光器件的亮度、效率和寿命,通常在器件中使用多层结构。这些多层结构包括发光层及各种辅助有机层,如:空穴注入层,空穴传输层,电子传输层等。而且,就最近的有机电致发光元件而言,为了解决在空穴输送层的发光问题,一直在研究着在空穴输送层与发光层之间使用发光辅助层的方法,由于根据各发光层(R、G、B)而所希望的物质的特性不同,使得现在需要开发根据各发光层的发光辅助层。这些辅助有机层有助于提高载流子(空穴和电子)在各层界面间的注入效率,平衡载流子在各层之间的传输,从而提高器件的亮度和效率。
有机电致发光材料的研究已经在学术界和工业界广泛开展,但目前为止还未充分开发出稳定又高效的有机电气元件用的有机物层材料,而且该技术的产业化进程仍面临许多关键问题,因此,开发新的材料,一直是本领域技术人员亟待解决的问题。

在6000(nits)亮度下对上述实施例21~40以及器件对比例1得到的有机电致发光器件的驱动电压、发光效率以及寿命进行表征,测试结果如下表2:
表2:
表2可以看出,使用本发明提供的发光辅助材料制备的有机电致发光器件与对比例1提供的现有的有机电致发光器件相比较而言,其驱动电压明显降低,发光效率和寿命得到显著提高。
本说明书中各个实施例采用递进的方式描述,每个实施例重点说明的都是与其他实施例的不同之处,各个实施例之间相同相似部分互相参见即可。对于实施例公开的装置而言,由于其与实施例公开的方法相对应,所以描述的比较简单,相关之处参见方法部分说明即可。
对所公开的实施例的上述说明,使本领域专业技术人员能够实现或使用本发明。对这些实施例的多种修改对本领域的专业技术人员来说将是显而易见的,本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下,在其它实施例中实现。因此,本发明将不会被限制于本文所示的这些实施例,而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
