1.现代社会竞争激烈，因此，每个学生一定要提高自我核心竞争力；
2.每个学生要努力践行
“养天地正气，法古今完人“的苏大校训，力求将自己培养成德才兼备的现代青年；
3.我们要努力创造OLED技术的自主知识产权，在我国形成“养土鸡--喂土饲料--生土鸡蛋”的全自主产业链发展模式；
4.学术报告中所使用的PPT演示文稿，是报告人的学术面容。我们一定要认真学会如何作学术报告、如何准备高质量的演示文稿，为今后的事业发展，不断提高学术交流能力；
5.想问题时，要异想天开；做事情时，要脚踏实地。

Two novel spiro-based host materials, namely 3-(9,9′-spirobi[fluoren]-6-yl)-9-phenyl-9H-carbazole (SF3Cz1) and 9-(3-(9,9′-spirobi[fluoren]-6-yl)phenyl)-9H-carbazole (SF3Cz2) were designed and synthesized. Due to the meta-linkage of spirobifluorene backbone, both SF3Cz1 and SF3Cz2 possess triplet energies over 2.70 eV, indicating they could serve as suitable hosts for blue and even white phosphorescent organic light-emitting diodes (PHOLEDs). The fabricated bis(4,6-(difluorophenyl)-pyridinato -N,C′)picolinate (FIrpic) based PHOLEDs hosted by SF3Cz1 and SF3Cz2 exhibited excellent performance with maximum external quantum efficiencies (EQEs) of 18.1% and 19.7%, respectively. Two-color warm white PHOLEDs fabricated by utilizing SF3Cz1 and SF3Cz2 as hosts also achieved high EQEs and low efficiency roll-offs. The results demonstrate that SF3Cz1 and SF3Cz2 are promising hosts for blue and white PHOLEDs.
