首次设计和合成了一种新的,新的电子不足的2,5-二氮杂咔唑(25NCz),其高T 1 = 2.77 eV,具有在光电领域构建有机电子材料的巨大潜力。在这里,引入25NCz作为大的刚性型外围官能团,通过接枝大的刚性型π共轭核心蒽,开发出新型的电子传输材料(ETM)。设计并开发了两种新颖的ETM p -S25NCzDPA和p -D25NCzDPA。由于25NCz具有刚性和电子接受性的双重特征如预期的那样,这两个ETM具有良好的热稳定性和高电子迁移率。当制造基于这两种新型ETM的三重态-三重态融合(TTF)天蓝色荧光OLED时,它们表现出卓越的性能。尤其是,对于基于p -S25NCzDPA的器件,最大外部量子效率(EQE)达到7.45%,并且在50,000 cd m -2的亮度下EQE保持7.45%。这项工作合理地证明了新开发的缺电子部分25NCz在设计用于高性能OLED的ETM中的重要性。

The palladium-catalysed cross-coupling reactions of arylboronic acids with a variety of pi-deficient heteroaryl chlorides proceed in high yield. [1,4-Bis(diphenylphosphino)butane]palladium(II) dichloride was found to be a very satisfactory catalyst for monocyclic heteroaryl chlorides, whereas tetrakis(triphenylphosphine)palladium(O) was found to be excellent for a range of chloroquinoline derivatives.
