Deep‐Red/Near‐Infrared Delayed Fluorescence Luminophores Based on Dipyrido[3,2‐a:2”,3”‐c]Phenazine‐11,12‐Dicarbonitrile for High‐Performance OLEDs (Advanced Optical Materials 14/2023)

In article number 2300404, Zujin Zhao and colleagues create efficient deep-red to near-infrared thermally activated delayed fluorescence molecules with extended π-conjugation and intramolecular hydrogen bonding, which exhibit high photoluminescence efficiencies and large horizontal dipole ratios and furnish the state-of-the-art deep-red to near-infrared organic light-emitting diodes, with outstanding external quantum efficiencies of up to 32.9%.
