Abstract

In the traditional molecular design of thermally activated delayed fluorescence (TADF) emitters composed of electron‐donor and electron‐acceptor moieties, achieving a small singlet–triplet energy gap (Δ E ST ) in strongly twisted structures usually translates into a small fluorescence oscillator strength, which can significantly decrease the emission quantum yield and limit efficiency in organic light‐emitting diode devices. Here, based on the results of quantum‐chemical calculations on TADF emitters composed of carbazole donor and 2,4,6‐triphenyl‐1,3,5‐triazine acceptor moieties, a new strategy is proposed for the molecular design of efficient TADF emitters that combine a small Δ E ST with a large fluorescence oscillator strength. Since this strategy goes beyond the traditional framework of structurally twisted, charge‐transfer type emitters, importantly, it opens the way for coplanar molecules to be efficient TADF emitters. Here, a new emitter, composed of azatriangulene and diphenyltriazine moieties, is theoretically designed, which is coplanar due to intramolecular H‐bonding interactions. The synthesis of this hexamethylazatriangulene‐triazine (HMAT‐TRZ) emitter and its preliminary photophysical characterizations point to HMAT‐TRZ as a potential efficient TADF emitter.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
