Simultaneous Manipulation of Intramolecular and Intermolecular Hydrogen Bonds in n‐Type Organic Semiconductor Layers: Realization of Horizontal Orientation in OLEDs

1,3,5-Triphenyltriazine-based electron transport materials form a highly horizontally oriented film by synergistic effect of intra- and intermolecular hydrogen bonds. Organic light-emitting devices employing this film as electron-transport layer can operate at an extremely low voltage and realize high power efficiency.
