Abstract
本发明提供了一种有机化合物,具有式Ⅰ所示结构。本发明提供的一系列化合物可以降低驱动电压,提高器件的发光效率和寿命,在电致发光技术领域中可得到较好的应用。
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。
有机电致发光材料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,制备的有机化合物作为磷光主体材料,可以提升OLED器件效率、寿命,降低驱动电压。
本发明提供了一种有机化合物,具有式Ⅰ所示结构:
其中,L1、L2、L3独立的选自单键、取代或非取代的亚芳基或亚杂芳基;
R1、R2、X独立的选自H、取代或非取代的芳基、杂芳基、芳胺基;
所述m、n独立的选自0~4的任意整数。
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发光层,所述发光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。本发明提供的一系列化合物可以降低驱动电压,提高器件的发光效率和寿命,在电致发光技术领域中可得到较好的应用。

表1OLED器件的性能评价结果
从表1可以看出,本发明提供的OLED器件具有较低的工作电压、较高的发光效率以及较长的寿命。相对于器件对比例,采用本发明化合物的OLED器件的工作电压得到降低,发光效率明显提升,寿命明显延长。这可能得益于本发明化合物特殊的结构,可实现HOMO、LUMO能级的较小重叠,实现较小的ΔEST,从而实现比较高效的RISC(反系间窜越)过程,达到较高的发光效率。本发明化合物具有优异的热稳定性和薄膜稳定性,在OLED器件工作时更加稳定,有利于OLED器件的制备和获得更长寿命,是一种性能优异的发光材料。
