Pure blue‐emitting organic light‐emitting diodes (OLEDs) based on dicyano‐imidazole with thermally activated delayed fluorescence (TADF) have been studied at Providence University (of which a building is shown). The efficiencies obtained in this work are the highest among the reported imidazole‐based TADF‐OLEDs. By combining these tailor‐made TADF compounds with specific device architectures, electroluminescent emission from sky blue to deep blue could be achieved.
