Autor: Guo-Xi Yang, Jie-Ji Zhu, Shan-Shun Tang, Hong-Ji Tan, Xin He, Jing-Xin Jian, Xu-Hui Zheng, Qing-Xiao Tong

Publikováno v: Advanced Photonics Research, Vol 2, Iss 7, Pp n/a-n/a (2021)

Of paramount significance in phosphorescent organic light‐emitting diodes (PHOLEDs) are the facts that Förster resonance energy transfer (FRET) must be sufficient and back energy transfer should be prohibited. Herein, the FRET efficiencies for hig

Constructing Highly Efficient Blue OLEDs with External Quantum Efficiencies up to 7.5 % Based on Anthracene Derivatives

Autor: Keng Chen, Jiuyan Li, Qing-Xiao Tong, Xu-Hui Zheng, Xiang Chen, An-Qi Lin, Tingting Huang, Guo-Xi Yang

Publikováno v: Chemistry – A European Journal. 27:16181-16188

Acquiring desirable device performance with deep-blue color purity that fulfills practical application requirements is still a challenge. Bipolar fluorescent emitters with hybrid local and charge transfer (HLCT) state may serve to address this issue.

Efficient deep blue OLEDs with extremely low efficiency roll-off at high brightness based on phenanthroimidazole derivatives

Autor: Xiang Chen, Shan-Shun Tang, Guo-Xi Yang, Jie-Ji Zhu, Qing-Xiao Tong, Xu-Hui Zheng, Silu Tao, Juewen Zhao

Publikováno v: Chinese Chemical Letters. 30:1989-1993

Phosphorescent and thermally activated delayed fluorescence (TADF) emitters can break through the spin statistics rules and achieve great success in external quantum efficiency (over 5%). However, maintaining high efficiency at high brightness is a t
