Description

一种含有二甲基蒽的有机化合物及其应用
技术领域
本发明涉及有机光电材料技术领域,尤其是涉及一种含有二甲基蒽结构为中心骨架的化合物材料及其在OLED领域的应用。
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。
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。
