    摘要: The invention relates to an organic molecule, in particular for the application in optoelectronic devices. According to the invention, the organic molecule has a structure of formula I: wherein RI, RII, RIII and RIV is independently from another selected from the group consisting of: hydrogen, deuterium, N(R5)2, OR5, SR5, Si(R5)3, B(OR5)2, OSO2R5, CF3, CN, halogen, C1-C40-alkyl, C1-C40-alkoxy, C1-C40-thioalkoxy, C2-C40-alkenyl, C2-C40-alkynyl, C6-C60-aryl, and C3-C57-heteroaryl, and RV is selected from the group of C1-C5 alkyl, C6-C18 aryl and C3-C15 heteroaryl.

    摘要: Organic molecules are provided for use in optoelectronic devices. The organic molecules are purely organic molecules, i.e., they do not contain any metal ions. The organic molecules exhibit emission maxima in the blue, sky-blue or green spectral range. The organic molecules exhibit emission maxima between 420 nm and 520 nm, between 440 nm and 495 nm, or 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 use of the molecules in an optoelectronic device, e.g., an organic light-emitting diode (OLED) leads to higher efficiencies of the device. Corresponding OLEDs have a higher stability than OLEDs with known emitter materials and comparable color.
