designed an ambipolar material, 3,7‐bis[4‐(N‐carbazolyl)‐phenyl]‐2,6‐diphenylbenzo[1,2‐b:4,5‐b′]difuran (CZBDF), and synthesized it by zinc‐mediated double cyclization. Its physical properties clarified that CZBDF possesses a wide‐gap character, well‐balanced and high hole and electron mobilities of larger than 10−3 cm2 V−1 s−1, and a high thermal stability. Using CZBDF as a host material for heterojunction
我们设计了一种双极性材料3,7-双[4-(N-咔唑基)-苯基] -2,6-二苯并苯并[1,2- b:4,5- b ']二呋喃(CZBDF),并进行了合成它是通过锌介导的双环化。它的物理性质表明,CZBDF具有宽的间隙特性,良好的平衡和高的空穴迁移率和电子迁移率,其迁移率大于10 -3 cm 2 V -1 s -1,并且具有很高的热稳定性。使用CZBDF作为异质结OLED器件的主体材料,可以获得全范围的可见光发射。值得注意的是,CZBDF还使我们能够制造出发射RGB的同质结OLED,其性能可与由多种材料组成的异质结器件相媲美或更高。
