本发明提供的化合物具有较高的空穴迁移率,高的空穴传输速率能够降低器件的起始电压,提高有机电致发光器件的效率;因本发明化合物以茚并蒽衍生物为核心,搭配长支链结构,具有较强的刚性,分子间不易结晶,不易聚集,具有良好的成膜性的特点。因此本发明化合物作为OLED发光器件的发光功能层材料使用时,搭配本发明范围内的支链可有提升器件的使用寿命和效率。

Description

一种以茚并蒽衍生物为核心的有机化合物及其应用
技术领域
本发明涉及半导体技术领域,尤其涉及一种以茚并蒽衍生物为核心的有机化合物及其应用。
背景技术
有机电致发光(OLED:Organic Light Emission Diodes)器件技术既可以用来制造新型显示产品,也可以用于制作新型照明产品,有望替代现有的液晶显示和荧光灯照明,应用前景十分广泛。OLED发光器件犹如三明治的结构,包括电极材料膜层,以及夹在不同电极膜层之间的有机功能材料,各种不同功能材料根据用途相互叠加在一起共同组成OLED发光器件。作为电流器件,当对OLED发光器件的两端电极施加电压,并通过电场作用有机层功能材料膜层中的正负电荷,正负电荷进一步在发光层中复合,即产生OLED电致发光。
当前,OLED显示技术已经在智能手机,平板电脑等领域获得应用,进一步还将向电视等大尺寸应用领域扩展,但是,和实际的产品应用要求相比,OLED器件的发光效率,使用寿命等性能还需要进一步提升。对于OLED发光器件提高性能的研究包括:降低器件的驱动电压,提高器件的发光效率,提高器件的使用寿命等。为了实现OLED器件的性能的不断提升,不但需要从OLED器件结构和制作工艺的创新,更需要OLED光电功能材料不断研究和创新,创制出更高性能OLED的功能材料。
应用于OLED器件的OLED光电功能材料从用途上可划分为两大类,即电荷注入传输材料和发光材料,进一步,还可将电荷注入传输材料分为电子注入传输材料、电子阻挡材料、空穴注入传输材料和空穴阻挡材料,还可以将发光材料分为主体发光材料和掺杂材料。
为了制作高性能的OLED发光器件,要求各种有机功能材料具备良好的光电特性,譬如,作为电荷传输材料,要求具有良好的载流子迁移率,高玻璃化转化温度等,作为发光层的主体材料要求材料具有良好双极性,适当的HOMO/LUMO能阶等。
构成OLED器件的OLED光电功能材料膜层至少包括两层以上结构,产业上应用的OLED器件结构,则包括空穴注入层、空穴传输层、电子阻挡层、发光层、空穴阻挡层、电子传输层、电子注入层等多种膜层,也就是说应用于OLED器件的光电功能材料至少包含空穴注入材料,空穴传输材料,发光材料,电子传输材料等,材料类型和搭配形式具有丰富性和多样性的特点。另外,对于不同结构的OLED器件搭配而言,所使用的光电功能材料具有较强的选择性,相同的材料在不同结构器件中的性能表现,也可能完全迥异。
因此,针对当前OLED器件的产业应用要求,以及OLED器件的不同功能膜层,器件的光电特性需求,必须选择更适合,具有高性能的OLED功能材料或材料组合,才能实现器件的高效率、长寿命和低电压的综合特性。就当前OLED显示照明产业的实际需求而言,目前OLED材料的发展还远远不够,落后于面板制造企业的要求,作为材料企业开发更高性能的有机功能材料显得尤为重要。
发明内容
针对现有技术存在的上述问题,本发明提供了一种以茚并蒽衍生物为核心的有机化合物及其在有机电致发光器件上的应用。本发明提供的有机化合物具有良好的热稳定性和较高的玻璃化温度,同时具有合适的HOMO能级,采用本发明提供的有机化合物的器件通过结构优化,可有效提升OLED器件的光电性能以及OLED器件的寿命。
具体技术方案如下:
