Direct Experimental Evidence of Hot-Exciton Channels via Anti-Kasha T2 Phosphorescence in High-Efficiency Red OLEDs.

High-efficiency red-emissive organic materials are crucial for full-color displays and solid-state lighting but remain fundamentally constrained by the energy-gap law, which accelerates non-radiative decay in low-bandgap systems. Herein, two asymmetric donor-acceptor-donor' (D-A-D') red emitters, PPIPP and PPIPOX, were...
