Cover Feature: Dicyano-Imidazole: A Facile Generation of Pure Blue TADF Materials for OLEDs (Chem. Eur. J. 51/2021)

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.
