本发明涉及新型的有机电子材料， 可以通过真空蒸渡沉积或者旋涂成薄膜， 应 用在有机电致发光二极管上， 属于有机电致发光器件领域。
背景技术
有机电致发光器件作为一种新型的显示技术， 具有自发光、 宽视角、 低能耗、 效率高、 薄、 色彩丰富、 响应速度快、 适用温度范围广、 低驱动电压、 可制作柔性 可弯曲与透明的显示面板以及环境友好等独特优点， 因此， 有机电致发光器件技术 可以应用在平板显示器和新一代照明上， 也可以作为 LCD的背光源。
有机电致发光器件为在两个金属电极之间通过旋涂或者真空蒸渡沉积一层有机 材料而制备的器件， 一个经典的三层有机电致发光器件包含空穴传输层， 发光层和 电子传输层。 由阳极产生的空穴经空穴传输层跟由阴极产生的电子经电子传输层结 合在发光层形成激子， 而后发光。 有机电致发光器件可以通过改变发光层的材料来 发射红光， 绿光和蓝光。 也可以通过在发光层进行材料搭配， 使器件发射白光。
可是， 现在的 OLED器件由于效率低， 使用寿命短等因素制约其应用， 因此要 改善这些条件的限制。 其中， 降低空穴注入 /传输材料与发光材料之间的能垒和提到 空穴传输材料的热稳定性有助于改善 OLED器件的效率和提高使用寿命。 另外， 由 于小分子的空穴注入 /传输材料的溶解性比较差， 只能通过蒸渡来制备器件， 不利于 商品化使用， 因此发展良好溶解性的高空穴迁移率的材料实现旋涂或者喷墨打印有 利于大面积应用。
已有使用的空穴注入材料 copper phthalocyanine (CuPc),其降解慢，制备耗能高， 不利于环境保护。而常见的空穴传输材料为 TPD和 NPB，尽管具有很好的空穴迁移 率， 分别是 1.0*10_3和 S. lO^ cm2^^1, 但是这两个材料的玻璃化温度分别为 65 °〇和981， 其稳定性还是远远不能满足 oled的应用需求。 因而， 需要发展高效和稳 定性的有机电致发光材料， 才能制备高效稳定的有机电致发光器件。 发明内容
本发明就是克服上面化合物的缺陷， 提供一系列具有较好热稳定性， 高空穴迁 移率和良好溶解性的空穴传输、 注入材料， 并通过这些材料制备制具有电致发光效 率良好和色纯度优异以及寿命长的有机电致发光器件。
本发明提供的有机电致发光器件， 该器件包含阳极， 阴极和一层或多层有机层。 所述有机层可以包括空穴注入层， 空穴传输层， 发光层， 空穴阻挡层， 电子传输层 和电子注入层。 需要特别指出， 上述有机层可以根据需要， 不必每层都存在。
一种有机电致发光器件， 包含阳极， 阴极和一层或多层有机层， 有机层中至少 有一层包含一种具有如下化学式 I所述结构式的材料：
