The design of an extended multiple resonance TADF emitter based on a polycyclic amine/carbonyl system
Dianming Sun,Dianming Sun,Subeesh Madayanad Suresh,David Hall,David Hall,Ming Zhang,Changfeng Si,David B. Cordes,Alexandra M. Z. Slawin,Yoann Olivier,Yoann Olivier,Xiaohong Zhang,Eli Zysman-Colman +12 more
TL;DR: In this article, a simple design strategy is introduced to construct an MR-TADF emitter, DDiKTa, through dimerization of the known MR-tadf emitter DiKTa.
Stable green phosphorescence organic light-emitting diodes with low efficiency roll-off using a novel bipolar thermally activated delayed fluorescence material as host
Kunping Guo,Hedan Wang,Zixing Wang,Changfeng Si,Cuiyun Peng,Guo Chen,Jianhua Zhang,Gaofeng Wang,Bin Wei +8 more
TL;DR: In this paper, a bipolar hosting material, 11-(3-(4,6-diphenyl-1,3,5-triazin-2-yl)phenyl)-12,12-dimethyl-11,12dihydroindeno[2,1-a]carbazole (DPDDC), was designed, synthesized, and characterized for green phosphorescent organic light-emitting diodes (PhOLEDs).

Judicious Heteroatom Doping Produces High Performance Deep Blue/Near UV Multiresonant Thermally Activated Delayed Fluorescence OLEDs.
Subeesh Madayanad Suresh,Le Zhang,Tomas Matulaitis,David Hall,Changfeng Si,Gaetano Ricci,Alexandra M. Z. Slawin,David Beljonne,Yoann Olivier,Ifor D. W. Samuel,Eli Zysman-Colman +10 more
TL;DR: In this paper , the authors presented two multi-resonant thermally activated delayed fluorescence (MR-TADF) emitters and showed how further borylation of a deep blue MR-TadF emitter, DIDOBNA-N, both blue shifts and narrows the emission producing a new near-UV MR-tadf emitter.

The synthesis of brominated-boron-doped PAHs by alkyne 1,1-bromoboration: mechanistic and functionalisation studies
Kang Yuan,Rachel J. Kahan,Changfeng Si,A. Williams,Sven Kirschner,Marina Uzelac,Eli Zysman-Colman,Michael J. Ingleson +7 more
TL;DR: The synthesis of a range of brominated-Bn-containing (n = 1, 2) polycyclic aromatic hydrocarbons (PAHs) is achieved simply by reacting BBr3 with appropriately substituted alkynes via a bromoboration/electrophilic C–H borylation sequence.
