Achieving Nearly 30% External Quantum Efficiency for Orange–Red Organic Light Emitting Diodes by Employing Thermally Activated Delayed Fluorescence Emitters Composed of 1,8-Naphthalimide-Acridine Hybrids
Weixuan Zeng,Hsin-Yu Lai,Wei-Kai Lee,Min Jiao,Yi-Jiun Shiu,Cheng Zhong,Shaolong Gong,Tao Zhou,Guohua Xie,Monima Sarma,Ken-Tsung Wong,Chung-Chih Wu,Chuluo Yang +12 more
TL;DR: This finding relaxes the usually stringent material requirements for effective TADF emitters by comprising smaller radiative transition rates and less than ideal ΦPL s.

Exciplex: An Intermolecular Charge-Transfer Approach for TADF
TL;DR: The working mechanisms of the direct electroluminescence from the donor/acceptor interface and the exciplex-forming systems as cohost for the realization of high efficiency OLEDs are reviewed and discussed.

TL;DR: A thermally activated delayed fluorescent emitter (DMAC-TRZ) was reported either as the emitting dopant in a host or as the non-doped (neat) emitting layer to achieve high EL EQEs of up to 26.5% and 20% in OLEDs, respectively.

TL;DR: Time-resolved kinetics lead us to conclude that CT excited states relax to a ground-state intermediate with a time constant of ~3 µs, followed by a structural relaxation to the original CN-Cz2:PO-T2T configuration within ~14 ²s.
Anomalously Long-Lasting Blue PhOLED Featuring Phenyl-Pyrimidine Cyclometalated Iridium Emitter
Monima Sarma,Wei-Lung Tsai,Wei-Kai Lee,Yun Chi,Chung-Chih Wu,Shih-Hung Liu,Pi-Tai Chou,Ken-Tsung Wong,Ken-Tsung Wong +8 more
TL;DR: In this paper, the authors proposed to replace pyridine in cyclometalating ligands in FIrpic with pyrimidine, which has a slightly red-shifted emission but shorter excited state lifetime and the capability to form a highly efficient blue phosphorescent organic light-emitting device (OLED) with long operation lifetime.
