Abstract (en)

[origin: WO2022013112A1] The present invention relates to compounds simultaneously having thermally activated delayed fluorescence (TADF), circularly polarised luminescence (CPL) and aggregation-induced emission enhancement (AIEE) properties. The invention also relates to the use of such compounds as a photocatalyst or as a dopant, in particular in the emitting layers of light-emitting diodes (OLEDs), as well as light-emitting devices or light-emitting diodes (OLEDs) comprising such compounds.
