Abstract:
The greatest challenge for modern OLEDs is achieving rapid emission from triplet states. I will describe a new approach to achieving sub-microsecond triplet harvesting using materials with a torsional degree of freedom. This allows access to excited states with high oscillator strength, high spin-orbit coupling and low exchange energy, enabling the most efficient printable OLEDs ever reported.
