Realization of deep-blue TADF in sterically controlled naphthyridines for vacuum- and solution-processed OLEDs

Narrow-band deep-blue (emission peak 80 nm) sky-blue (λmax ≈ 480 nm) emission. The demonstrated emitters are among the best-performing conventional D-A-type blue/deep-blue TADF emitters in terms of EQE and efficiency roll-off properties of their devices.
