Abstract
In an electroluminescent excitation, singlet and triplet excitons are generated. In this contribution it is proposed to harvest all excitons in an efficiently emitting singlet state by use of molecules which exhibit distinct thermally activated delayed fluorescence at T = 300K. Highly attractive examples, comprising Cu(I) complexes and the metal-free acridine orange, are presented and discussed with respect to their photophysical properties.
