Fluorine-free, highly efficient, blue-green and sky-blue-emitting cationic iridium complexes were developed, which showed high performances in organic light-emitting diodes.
A cationic iridium complex with an electron-transporting counter-anion was developed, which showed superior performance in solution-processed phosphorescent light-emitting diodes.
Through carbazole modification, two new emitters with different emitting mechanisms were synthesized to obtain deep blue and pure OLEDs CIE coordinates of (0.164, 0.077) (0.157, 0.107) EQE max 4.6% 8.7%, respectively.
By incorporating a methoxy group at the 6- and 7-sites of quinazoline ring phenylquinazoline cyclometalating ligands, iridium complexes realize pure red phosphorescence. The PHOLED based on Ir2 achieves CIE (0.65, 0.34) higher external quantum efficiency 26.22%.
The diphenylvinyl motif with rotary phenyl rings has been widely used as a building block for the construction of luminescent materials aggregation-induced emission (AIE) properties. Here, we report use 2,2-diphenylvinyl in an iridium complex and its influence on luminescence properties complex. Surprisingly, attached to cyclometalating ligand brings about no AIE; instead, it completely quenches phosphorescence from solution or films at room temperature 77 K. Hydrogenation vinyl group...
The synergistic regulation of cyclometalating ligands and ancillary ligand optimized both the blue color purity high efficiencies iridium complexes. A EQE 28.0% with CIE (0.16, 0.21) was achieved in a phosphorescent OLED.
A group of D-A-D type thermally activated delayed fluorescence (TADF) emitters were developed with 10-(pyridin-2-yl)acridin-9(10H)-one as acceptor and substituted carbazoles donors. The design was focused on incorporating pyridyl to the 10-site nitrogen atom acridin-9(10H)-one ring, which improved reverse intersystem crossing rate constant kRISC from 103 s-1 105 s-1. More importantly, linkage uniquely its 2-position ring induced intramolecular hydrogen bond, suppressed nonradiative...
