Description
技术领域
本发明涉及光电材料技术领域,更具体而言,涉及基于杂环并嘧啶类有机单分子双发射材料及其制备与应用。
背景技术
近年来,白光有机发光二极管(WOLED)具有对比度高、视角广、自发光、驱动电压低、柔韧性好、重量轻等诸多独特优点,受到人们的广泛关注。通常,白光是由红、绿和蓝三基色或者蓝光和黄光相混合形成的复合光。相反,通过单分子产生用于覆盖整个可见光区域的两个或两个以上的发射波段,进而制造出具有高性能的WOLED的有机材料相对较少,并且大部分仅发生在溶液体系中。而通过多发光层产生白光发射很容易产生相分离,发光稳定性差,制备工艺复杂等问题。
另一方面,基于单线态发光的有机发光二极管(OLED)由于只能利用所注入的单线态激子,故其器件内量子效率的理论极限值仅为25%,并伴随有超过75%的能量流失;而基于三线态发光的磷光材料,热激活延迟荧光(TADF)则能充分利用所注入的三线态激子使得其器件内量子效率能达到100%。相对来讲,通过同时利用单线态和三线态激子同时发射可以有效的实现单分子的双重荧光发射。大多数的磷光材料都是基于铱(Ir)和铂(Pt)等不可再生的贵重金属离子所形成的配合物,其高昂的价格使得OLED器件的制备成本大幅度提高,不利用大规模的生产使用。
