Abstract: Provided is an organic electroluminescent element having high efficiency, a long lifetime, and bending resistance. An organic electroluminescent element includes a light emitting layer and an electron transport layer adjacent to the light emitting layer between a positive electrode and a negative electrode. A host compound of the light emitting layer has an ionization potential deeper than that of a light emitting dopant of the light emitting layer by 0.3 eV or more. At least one organic compound contained in the electron transport layer has a molecular dipole moment of 6.0 debye or more.
Abstract: 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.
