چکیده
A multi-resonance thermally activated delayed fluorescence (MR-TADF) dendrimer emitter and a related reference MR-TADF compound were designed, synthesized, characterized for use as narrowband emitters in solution-processed OLEDs. The 1 wt% doped films PMMA film revealed that the compounds MR-D1 MR-D2 showed green emission at λPL of 490 495 nm with FWHM 23 29 nm, respectively. 50 mCP still show 499 28 MR-D2, respectively, while conserving small ΔEST 0.14 0.13 eV, OLEDs containing an emissive layer consisting high EQEmax 27.7% 21.0%, low efficiency roll-off 19% 30% luminance 2000 cd/m−2.

متن کاملAn Alternative Host Material for Long‐Lifespan Blue Organic Light‐Emitting Diodes Using Thermally Activated Delayed Fluorescence
It has been challenging to find stable blue organic light emitting diodes (OLEDs) that rely on thermally activated delayed fluorescence (TADF). Lack of stable host materials well-fitted to the TADF emitters is one of the critical reasons. The most popular host for blue TADF, bis[2-(diphenylphosphino)phenyl] ether oxide (DPEPO), leads to unrealistically high maximum external quantum efficiency. ...
