Abstract

一种化合物、包含该化合物的有机电致发光器件及其应用,化合物具有如(I)所示的结构。

Description

一种化合物、包含其的有机电致发光器件及其应用 技术领域
本发明涉及有机发光化合物及有机电子发光器件领域,尤其涉及一种化合物、包含该化合物的有机电致发光器件及其应用。
背景技术
近年来,基于有机材料的光电子器件已经变得越来越受欢迎。有机材料固有的柔性令其十分适合用于在柔性基板上制造,可根据需求设计、生产出美观而炫酷的光电子产品,获得相对于无机材料无以比拟的优势。此类有机光电子器件的示例包括有机发光二极管(OLED),有机场效应管,有机光伏打电池,有机传感器等。其中OLED发展尤其迅速,已经在信息显示领域取得商业上的成功。OLED可以提供高饱和度的红、绿、蓝三颜色,用其制成的全色显示装置无需额外的背光源,具有色彩炫丽,轻薄柔软等优点。
随着OLED在照明和显示两大领域的不断推进,人们对于其核心材料的研究也更加关注。这是因为一个效率好、寿命长的OLED器件通常是器件结构以及各种有机材料的优化搭配的结果。为了制备驱动电压更低、发光效率更好、器件使用寿命更长的OLED发光器件,实现OLED器件的性能不断提升,不仅需要对OLED器件结构和制作工艺进行创新,更需要对OLED器件中的光电功能材料不断研究和创新,以制备出具有更高性能的功能材料。基于此,OLED材料界一直致力于开发新的有机电致发光材料以实现器件低启动电压、高发光效率和更优的使用寿命。
目前,人们已经开发出多种有机材料,结合各种奇特的器件结构,可以提升载流子迁移率、调控载流子平衡、突破电致发光效率、延缓器件衰减。出于量子力学的原因,常见的荧光发光体主要利用电子和空穴结合时产生的单线态激子发光,现在仍然广泛地应用于各种OLED产品中。有些金属络合物如铱络合物,可以同时利用三线态激子和单线态激子进行发光,被称为磷光发光体,其能量转换效率可以比传统的荧光发光体提升高达四倍。热激发延迟荧光(TADF)技术通过促进三线态激子朝单线态激子的转变,在不采用金属配合物的情况下,仍然可以有效地利用三线态激子而实现较高的发光效率。热激发敏化荧光(TASF)技术则采用具TADF性质的材料,通过能量转移的方式来敏化发光体,同样可以实现较高的发光效率。然而,磷光主体材料在发光性能方面例如载流子传输能力等仍然存在较大的改进空间。
随着OLED产品逐步进入市场,人们对这类产品的性能有越来越高的要求。当前使用的OLED材料和器件结构无法完全解决OLED产品效率、寿命、成本等各方面的问题。因此,本 领域亟待开发更多种类、更高性能的OLED材料,以提升器件性能。

本发明提供上述化合物在有机电致发光器件中的应用。上述化合物优选用作有机电致发光器件的电子阻挡层材料。
本发明提供一种有机电致发光器件,包括基板、第一电极、第二电极以及位于所述第一电极和第二电极之间的至少一层有机层,所述有机层中包含至少一种上述化合物。优选所述有机层包括电子阻挡层,且所述电子阻挡层中含有上述化合物。
<发明效果>
本发明通过设计“萘三芳胺”的结构,能够有效地调控目标分子的三线态能级,从而获得空穴传输性能好、三线态能级高的新型空穴传输材料。具体而言,通过将“萘三芳胺”设为萘环上二芳基胺基的邻位存在取代或未取代的C 6-C 30芳基或者取代或未取代的C 3~C 30杂芳基的结构,或者,将“萘三芳胺”设为三“芳基”胺中的一个芳基为联萘基、另一个芳基为取代或未取代的苯并二甲基芴基、且第三个芳基为取代或未取代的C 6-C 30芳基或者取代或未取代的C 3~C 30杂芳基的结构,就能调高分子的三线态能级,得到空穴传输性能好的新型空穴传输材料。
在萘环上二芳基胺基的邻位存在上述特定取代基的情况下,若进一步在分子的特定位点引入环烷基,则可以促进分子采取平面铺展的排列,在提升载流子传输性能的同时也能提高光取出效率,从而提升器件的光电、寿命性能,使该材料作为有机电致发光器件的空穴传输层材料或者电子阻挡层时,可以提高发光效率、降低启动电压及延长器件的使用寿命;若上述分子的萘环1-位上连接有另一个萘环,而2-位与二芳胺基相连,则本发明化合物具有大π平面结构,能有效改变分子空间结构,有利于改善膜内分子堆积,且由于邻位取代限制了N原子上芳环的转动,增强了该类材料的稳定性,使得利用该化合物作为有机电致发光器件的空穴传输层材料和/或电子阻挡层时,可以提高发光效率,降低启动电压,并且使得器件具有更长的使用寿命。
在芳胺中含有与氮相连的联萘基、苯并芴基和特定的芳香基团的情况下,化合物具有良好的空穴注入及空穴传输性能、良好的折光系数、较高的相变温度,将其用于器件中可以提高OLED器件的发光效率,降低驱动电压,延长使用寿命。

对由上述过程制备的有机电致发光器件进行如下性能测定:
(1)在同样亮度下,使用数字源表(Keithley2400)及亮度计(ST-86LA型亮度计,北京师范大学光电仪器厂)测定实施例1-1~1-25和比较例1-1~1-2制备得到的有机电致发光器件的驱动电压和电流效率以及器件的寿命。具体而言,以每秒0.1V的速率提升电压,测定当有机电致发光器件的亮度达到5000cd/m 2时的电压即驱动电压,同时测出此时的电流密度;亮度与电流密度的比值即为电流效率;
(2)LT95的寿命测试如下:使用亮度计在5000cd/m 2亮度下,保持恒定的电流,测量有机电致发光器件的亮度降为4750cd/m 2的时间,单位为小时。
测试结果见表1。
表1
Figure PCTCN2020083499-appb-000182
从表1结果可以看出,本发明所述化合物用于有机电致发光器件的空穴传输材料时,器件亮度达到5000cd/m 2时,驱动电压低至5.0V以下,电流效率高达12.8cd/A以上,和比较例1-1~1-2相比,可以有效的降低驱动电压、提高电流效率,是性能良好的电子阻挡材料。其原因尚不明确, 但推测如下:与比较例1-1的化合物R-1相比,本发明实施例1-1~1-25的化合物用作有机电致发光器件的电子阻挡材料时,由于具有特定位置取代的环烷基,且在萘环上胺基的邻位具有芳香取代基,从而可以促进分子在器件平面上进行铺展,诱导其后沉积的发光层分子也采取如此的平面空间堆叠;而以平面铺展的方式堆叠的发光分子有利于提升光取出效率,从而提升电流效率。而比较例1-2所采用的化合物R-2,只是缺少了在胺基邻位的芳香取代基,竟也无法实现高的效率,且电压也居高不下,可见该类分子无法实现本发明化合物所具有的有利分子排列。以上分析足见本发明化合物之独特分子结构,是实现器件实施例所表现优异性能的关键所在。使用本发明的化合物的有机电致发光器件亮度达到5000cd/m 2时,驱动电压低至5.0V及以下,电流效率高达12.8cd/A及以上,LT95达到21h及以上。

实施例2-35~2-71、比较例2-5~2-8的制作过程同实施例2-34,区别是将化合物N1分别替换为表3中所示的化合物作为电子阻挡层材料。
对实施例2-34~2-71以及比较例2-5~2-8制备的有机电致发光器件进行如下性能测定:
在同样亮度下,使用数字源表及亮度计测定实施例2-34~2-71以及比较例2-5~2-8中制备得到的有机电致发光器件的驱动电压和电流效率以及器件的寿命。具体而言,以每秒0.1V的速率提升电压,测定当有机电致发光器件的亮度达到3000cd/m 2时的电压即驱动电压,同时测出此时的电流密度;亮度与电流密度的比值即为电流效率;LT95的寿命测试如下:使用亮度计在5000cd/m 2亮度下,保持恒定的电流,测量有机电致发光器件的亮度降为4750cd/m 2的时间,单位为小时,测定结果如表3所示。

Figure PCTCN2020083499-appb-000187
Figure PCTCN2020083499-appb-000188
由表3中数据可以看出,本发明实施例2-34~2-71的化合物用于有机电致发光器件的电子阻挡层材料时,器件亮度达到3000cd/m 2时,驱动电压低至3.8V以下,电流效率高达12.5cd/A以上;LT95达到167h以上,可以有效的降低驱动电压、提高电流效率、延长器件使用寿命,是性能良好的电子阻挡层材料。与此相对,使用了比较例2-5~2-8的化合物作为电子阻挡层材料的有机电致发光器件在驱动电压、电流效率、使用寿命等方面均存在不同程度的不足。其原因尚不明确,但推测如下:比较例2-5和2-6中使用的化合物EMT-1和EMT-2的分子结构中,R 2为芳胺基;比较例2-7和2-8中使用的化合物EMT-3和EMT-4的分子结构中,萘环上的芳胺基与萘基不处于邻位;这些化合物均不满足本发明权利要求1的限定,因此无法实现本发明的技术效果。
从上述结果可知,上述化合物既能作为HTL(空穴传输)材料使用,也可以同其他空穴传输材料搭配作为EBL(电子阻挡层)材料使用。当其作为空穴传输材料使用时,所有实施例的电压均显著降低、性能和寿命明显提高。当其作为EBL材料同其他空穴传输材料搭配使用时,所有实施例的器件电压略有升高,但器件的效率和寿命均进一步大幅提升。根据本发明化合物的分子结构模型图(图1和图2)与对比化合物的分子结构模型图(图3和图4)的对比可以得出,本发明提供的邻位取代萘基的联萘化合物不仅保留了对比例化合物(例如EMT-3~EMT-4)的大π平面结构,同时能有效改变分子空间结构,有利于改善膜内分子堆积,从而导致该类材料同对比例相比具有更好的效率;进一步的高斯计算(Gaussian)表明,由于同时由于邻位取代限制了N原子上芳环的转动,从而增强了该类材料的稳定性,因而材料具有更长的使用寿命。

把上述带有阳极的玻璃基片置于真空腔内,抽真空至小于1×10 -5Pa,在上述阳极层膜上真空蒸镀HI-3作为空穴注入层,蒸镀速率为0.1nm/s,蒸镀膜厚为10nm;

测定结果如表4所示。
表4
Figure PCTCN2020083499-appb-000190
从表4的结果可以看出,本发明提供的化合物用于有机电致发光器件的电子阻挡层材料时,器件亮度达到5000cd/m 2时,驱动电压低为4.5~5.2V,电流效率为16.4~18.3cd/A,可以有效的降低驱动电压、提高电流效率、延长器件使用寿命,是性能良好的电子阻挡材料。
比较例1-1所使用的电子阻挡层材料C1中取代在萘环上的基团为苯基,不存在本发明中的联萘基团,因此比较例1-1的器件的性能相较于实施例明显下降,驱动电压高达5.5V,电流效率仅为13cd/A。
显然,上述实施例仅仅是为清楚地说明所作的举例,而并非对实施方案的限定。对于所属领域的普通技术人员来说,在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方案予以穷举。而由此所引伸出的显而易见的变化或变动仍处于本发明创造的保护范围之中。
