Spontaneous exciton dissociation enables spin state interconversion in delayed fluorescence organic semiconductors

Spontaneous exciton dissociation enables spin state interconversion in delayed fluorescence organic semiconductors

A low singlet-triplet energy gap, necessary for delayed fluorescence organic semiconductors, results in a small radiative rate that limits performance in OLEDs. Here, the authors show that it is possible to reconcile these conflicting requirements in materials that can access both high oscillator st...
