报告摘要:

In recent years, the cyclometalated Pt(II) and Ir(III) complexes with different ligands have been used as prospective blue phosphorescent materials. For improving this material further, the introduction of o-carborane is treated as an excellent strategy to promote the luminescent efficiency for Pt complexes. A series of new materials show over 82% phosphorescence quantum yield and good stability, but still it is not elucidated in the round. In my work, stable o-carborane cages are introduced into the traditional C, N, C-cyclometalated Pt(II) complexes in turn to explore its influence completely in contrast to original phenyl ligand from the view of theoretical investigation. Unlike traditional strategies on enhancing the radiative decay process, or reducing the non-radiative decay process, through cumbersome ligands decorations, our simple and controllable deuteriation strategy which is insensitive to the radiative decay process, enable to suppress the non-radiative decay process by almost a half for homoleptic or heteroleptic Ir(III) complexes. The strategies mentioned above can provide a viable guideline for design and regulate several aspects of highly efficient blue phosphorescent materials.


报告人简介:

Fu-Quan Bai obtained his B.Sc. in Chemistry from Jilin University in 2004. In 2009, he obtained his Ph.D. degree under the supervision of Academician Prof. Chia-Chung Sun and Prof. Hong-Xing Zhang from Jilin University. And then, he was worked as research associate in institute of theoretical chemistry of Jilin University. 2012-2013, he started his first postdoctoral training at Fukui research center, Kyoto University (Prof. Nakatsuji and Prof. Hasegawa, Japan). After returning changchun, he was hired as an associate professor in Jilin University to the present. In the meantime, he also worked as a visiting scientist (2016-2017) at the department of chemistry, Hong Kong University of Science and Technology (Prof. Zhenyang LIN). He has authored around 100 scientific publications and 2 patents and 2 book chapters.
