Description

一种有机电致发光化合物及其应用 技术领域
本发明涉及半导体技术领域，尤其是涉及一种荧光化合物的合成，以及作为发光层材料在有机发光二极管上的应用。
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。
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。
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。
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和空穴注入传输材料，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，作为发光层的材料要求材料具有良好的荧光量子效率、材料蒸镀稳定性、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、发光层、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，电子注入材料等，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。
目前，荧光材料研究方面已经取得了长足的发展，能够满足产业化的需求；但是其效率、寿命方面依然存在不足，不易达到全彩RGB的要求。因而，具有高效率、长寿命的荧光材料的研究和开发一直是产业化的热点。
因此，针对当前OLED显示照明产业的实际需求而言，荧光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荧光材料显得尤为重要。
发明内容
针对现有技术存在的上述问题，本申请人提供了一种有机电致发光化合物及其应用。本发明化合物作为发光层主体材料或者掺杂材料制作出的OLED器件具有良好的外量子效率、材料稳定性以及色纯度，能够满足面板制造企业的要求。

如图1所示，透明基板层1用透明材料，如玻璃。对透明的ITO阳极层2(膜厚为150nm)进行洗涤，即依次进行碱洗涤、纯水洗涤、干燥后再进行紫外线-臭氧洗涤以清除透明ITO表面的有机残留物。
在进行了上述洗涤之后的ITO阳极层2上，利用真空蒸镀装置，蒸镀HAT-CN，其膜厚为10nm，这层有机材料作为空穴注入层3使用。紧接着蒸镀60nm厚度的TCTA(4,4',4″-三(咔唑-9-基)三苯胺)作为空穴传输层4。
上述空穴传输材料蒸镀结束后，制作OLED发光器件的发光层5，其结构包括OLED发光层5所使用材料CBP【4,4'-二(9-咔唑)联苯】作为主体材料，MQAB作为掺杂材料，掺杂比例为5％重量比，发光层5膜厚为25nm。
在上述发光层5之后，继续真空蒸镀电子传输层材料为Alq3(8-羟基喹啉铝)。该材料的真空蒸镀膜厚为30nm，此层为电子传输层6。
在电子传输层6上，通过真空蒸镀装置，制作膜厚为1nm的氟化锂(LiF)层，此层为电子注入层7。
在电子注入层7上，通过真空蒸镀装置，制作膜厚为80nm的铝(Al)层，此层为阴极反射电极层8使用。各层材料结构如下所示：
