Description
技术领域
本发明涉及有机电致发光材料技术领域,尤其涉及一种有机化合物及其电致发光的应用。
背景技术
有机电致发光材料(OLED)作为新一代显示技术,具有超薄、自发光、视角宽、响应快、发光效率高、温度适应性好、生产工艺简单、驱动电压低、能耗低等优点,已广泛应用于平板显示、柔性显示、固态照明和车载显示等行业。
按发光机理可分为电致荧光和电致磷光两种,荧光是单重态激子的辐射衰减跃迁,磷光则是三重态激子辐射衰减到基态所发射的光。根据自旋量子统计理论,单重态激子和三重态激子的形成概率比例是1:3。荧光材料内量子效率不超过25%的限制,外量子效率普遍低于5%;电致磷光材料的内量子效率理论上达到100%,外量子效率可达20%。1998年,我国吉林大学的马於光教授和美国普林斯顿大学的Forrest教授分别报道了采用锇配合物和铂配合物作为染料掺杂入发光层,第一次成功得到并解释了磷光电致发光现象,并开创性的将所制备磷光材料应用于电致发光器件。
由于磷光重金属材料有较长的寿命(μs),在高电流密度下,可能导致三线态-三线态湮灭和浓度淬灭,造成器件性能衰减,因此通常将重金属磷光材料掺杂到合适的主体材料中,形成一种主客体掺杂体系,使得能量传递最优化,发光效率和寿命最大化。在目前的研究现状中,重金属掺杂材料商业化已成熟,很难开发可替代的掺杂材料。因此,把重心放在研发磷光主体材料是研究者们共通的思路。
现在使用的磷光材料存在寿命不够长,效率不够高及驱动电压比较高的缺陷,是目前亟需解决的问题。
发明内容
有鉴于此,本发明要解决的技术问题在于提供一种有机化合物及其电致发光的应用,可以有效提升器件的发光效率和寿命。
本发明提供了一种有机化合物,具有式Ⅰ所示结构:
其中,R1选自取代或未取代的芳基、杂芳基或芳胺基;
R2选自取代或未取代的芳基或杂芳基。
本发明提供了一种有机发光器件,所述有机发光器件包括阳极、阴极,以及位于所述阳极和阴极之间的有机薄膜层,所述有机薄膜层包括空穴传输层,所述空穴传输层中含有至少一种上述有机化合物。
本发明提供了一种有机发光器件,所述有机发光器件包括阳极、阴极,以及位于所述阳极和阴极之间的有机薄膜层,所述有机薄膜层包括电子阻挡层,所述电子阻挡层中含有至少一种上述有机化合物。
本发明提供了一种显示面板,包括上述有机发光器件。
与现有技术相比,本发明提供了一种有机化合物,具有式Ⅰ所示结构。本发明提供了一种以N原子杂环为骨架的发光层主体材料,具有合适的LUMO和HOMO值,同时其具有较高的三线态能级,可以有效阻挡激子的传输,将激子限制在发光层中,提升空穴的传输,利于提升器件的发光效率和寿命。

OLED器件的制备步骤如下:
(1)将玻璃基板1切成50mm×50mm×0.7mm的大小,分别在异丙醇和去离子水中超声处理30min,然后暴露在臭氧下清洁10min;将通过磁控溅射所得的具有ITO阳极2的玻璃基板安装到真空沉积设备上;
(2)在真空度为2×10-6Pa下,在ITO阳极层2上真空蒸镀化合物HAT-CN,厚度为10nm,作为第一空穴传输层3;
(3)在第一空穴传输层3上真空蒸镀化合物TAPC作为第二空穴传输层4,厚度为95nm;

所述OLED器件中用到的化合物结构如下:
应用例2~8
将应用例1中步骤(4)中的有机化合物H1分别替换为等量的化合物H3、H10、H23、H33、H78、H88或H94,其他制备步骤同应用例1。
对比例
一种OLED器件,其与应用例1的区别仅在于,将步骤(4)中的主体材料用等量的对比化合物HH替换;其它原料及制备步骤均相同。
OLED器件的性能评价:
用Keithley 2365A数字纳伏表测试OLED器件在不同电压下的电流,然后用电流除以发光面积得到OLED器件在不同电压下的电流密度;用Konicaminolta CS-2000分光辐射亮度计测试OLED器件在不同电压下的亮度和辐射能流密度;根据OLED器件在不同电压下的电流密度和亮度,得到在相同电流密度下(10mA/cm2)的启亮电压和电流效率(CE,Cd/A),Von为亮度1Cd/m2下的启亮电压;通过测量OLED器件的亮度达到初始亮度的95%时的时间而获得寿命LT95(在50mA/cm2测试条件下);具体数据如表1所示。
表1 OLED器件性能检测结果
从表1可以看出,相较于对比例(REF)的有机电致发光器件,应用例1-8的有机电致发光器件性能得到大幅提升。主要体现为器件的驱动电压降低了3.6%以上,效率提升了6.1%以上,而器件的LT95寿命提升了5.9%以上。这可能是因为本发明特殊的结构,本发明以吲哚基团与类吖啶基团稠合形成核心基团,吲哚并类吖啶衍生物作为发光层的主体材料时,由于其较大的电子云密度,使发光层的空穴迁移率得以提升,有助于有机发光层中的电子与空穴达到平衡,提高电致发光器件的发光效率以及降低有机电致发光器件的驱动电压。吲哚与类吖啶基团进行键合,降低了分子对称性,可以改善化合物的成膜性,从而提高电流效率和发光效率。
以上实施例的说明只是用于帮助理解本发明的方法及其核心思想。应当指出,对于本技术领域的普通技术人员来说,在不脱离本发明原理的前提下,还可以对本发明进行若干改进和修饰,这些改进和修饰也落入本发明权利要求的保护范围内。
