Description

一种含有苯并咔唑结构的衍生物及其制备方法和有机电致发 光器件
技术领域
本发明涉及有机光电材料技术领域,具体涉及一种含有苯并咔唑结构的衍生物及其制备方法和有机电致发光器件。
背景技术
随着信息产业的进步,传统的显示器已不能满足人们的要求,如:阴极射线管(cathode ray tube,CRT)显示器体积大、驱动电压高;液晶显示器(liquid crystaldisplay,LCD)亮度低、视角窄、工作温度范围小;等离子显示器(plasma display panel,PDP)造价昂贵、分辨率不高、耗电量大。
有机电致发光二极管(organic light-emitting diodes,OLEDs)作为一种全新的显示技术在各个性能上拥有现有显示技术无以伦比的优势,如具有全固态、自主发光、亮度高、高分辨率、视角宽(170度以上)、响应速度快、厚度薄、体积小、重量轻、可使用柔性基板、低电压直流驱动(3-10V)、功耗低、工作温度范围宽等,使得它的应用市场十分广泛,如照明系统、通讯系统、车载显示、便携式电子设备、高清晰度显示甚至是军事领域。
有机电致发光材料在近些年内不断实现突破,取得了令人瞩目的进展,对传统的显示材料构成了强有力的挑战。柔性OLED商业化以后,目前世界上与之相关的科研及商业力量都在不遗余力的开展这方面的工作。虽然有机电致发光材料研究已经取得巨大的成果,但是OLED在商业化的过程中还有一些亟待解决的问题。目前空穴传输材料大多采用具有二苯胺或咔唑结构,含有此类结构的器件缺陷是,发射光线发光度的改进伴随发光效率明显降低,尤其是,在无源驱动的情况下,对于实际应用来说,瞬间需要数千cd/m2或者更高的亮度,并且在高亮度区中发光效率的增加是重要的。然而,由于高亮度区域中三线态失活占优势地位,因此目前实际应用的空穴传输材料的条件下,发光效率的降低不能得到改进。
发明内容
