Organic light-emitting diodes based on phthalimide derivatives: improvement of the electroluminescence properties

HIGHLIGHTS

• who: Frédéric Dumur and collaborators from the A singlet emitter previously reported in the literature has been revisited in the context of multilayered devicesBy optimizing the device tacking, a, fold enhancement of the current efficiency was determined. Parallel to this, a device lifetime comparable to that obtained with a standard triplet emitter was obtained, demonstrating the viability of the approach. Phthalimide-based emitters deserve to be more widely studied for the design of OLEDs, even in the context of the last generation of light-emitting materials, namely the Thermally Activated Delayed Fluorescence (TADF) emitters.
