    摘要: Organic molecules are provided that exhibit emission maxima in the blue, sky-blue or green spectral range. The organic molecules exhibit emission maxima between 420 nm and 520 nm, preferably between 440 nm and 495 nm, more preferably between 450 nm and 470 nm. The photoluminescence quantum yields of the organic molecules are 20% or more. The molecules exhibit thermally activated delayed fluorescence (TADF). The molecules can be used in an optoelectronic device, for example an organic light-emitting diode (OLED), leading to higher efficiencies of the device. Corresponding OLEDs have a higher stability than OLEDs with known emitter materials and comparable color.
