We demonstrate a novel pathway to open an ultimate electroluminescence (EL) efficiency by using simple aromatic compounds displaying efficient thermally activated delayed fluorescence (TADF) having high photoluminescence (PL) efficiency. We found that a proper design of organic molecules enables the formation of a small energy gap between singlet and triplet excited states, resulting in the enhanced T1 to S1 reverse intersystem crossing (ISC). We also demonstrate very high efficiency EL using a new series of TADF materials. |
