Description

一种螺环化合物及其应用 技术领域
本发明涉及有机电致发光技术领域,尤其涉及一种适合有机电致发光器件的有机发光材料,特别涉及一种螺环化合物及其应用。
背景技术
目前,作为新一代显示技术的有机电致发光器件(OLED)在显示和照明技术方面都获得了越来越多的关注,应用前景十分广泛。但是,和市场应用要求相比,OLED器件的发光效率、驱动电压、使用寿命等性能还需要继续加强和改进。
一般来说,OLED器件基本结构为在金属电极中间夹杂各种不同功能的有机功能材料薄膜,犹如一个三明治的结构,在电流的驱动下,从阴阳两极分别注入空穴和电子,空穴和电子在移动一段距离后,在发光层得到复合,并以光或热的形式进行释放,从而产生了OLED的发光。然而,有机功能材料是有机电致发光器件的核心组成部分,材料的热稳定性、光化学稳定性、电化学稳定性、量子产率、成膜稳定性、结晶性、色饱和度等都是影响器件性能表现的主要因素。
为了得到性能优异的有机发光器件,材料的选择显得尤为重要,这不仅包括起到发光作用的发射体材料,还包含在器件中主要作用为载流子注入和传输的空穴注入材料、空穴传输材料、主体材料、电子传输材料、电子注入材料等功能性材料,他们的选择与优化可以提高空穴和电子的传输效率,使器件中的空穴和电子达到均衡,从而改善器件电压、发光效率和寿命。
