Compounds that are organic radicals that can have a dual function. The compounds can be fluorescent emitters that emit in the near-IR. The compounds can also facilitate reverse intersystem crossing (RISC) to convert triplet excitons in an OLED to singlet excited states to maximize utilization of generated excitons in the OLED and approach 100% internal quantum efficiency.
The invention relates to compounds with benzindenofluorene base bodies having a structure of formula (I):
and to the use thereof in electronic devices, in particular in organic electroluminescent devices.
