extended π‐conjugated molecule with both a high triplet state energy level and excellent thermal and morphological stability. As a proof of concept, dihydroindenofluorenes were used as the host in sky‐blue phosphorescent organic light‐emitting diodes (PhOLEDs) with high performance.
这项工作报告的第一结构,性质的关系研究邻[2,1 Ç ] - ,元[1,2一] - ,和对[1,2- b ] dihydroindenofluorenes,突出桥梁硬化对影响电子特性。这项研究使设计出既具有高三重态能级又具有出色的热和形态稳定性的扩展π共轭分子成为可能。作为概念验证,dihydroindenofluorenes用作在天蓝色
