Non-doped organic light-emitting diodes (OLEDs) possess merits of higher stability and easier fabrication than doped devices. However, luminescent materials with high exciton use are generally unsuitable for non-doped OLEDs because of severe emission quenching and exciton annihilation in neat films.

Angewandte Chemie (International ed. in English), 58(2), 582-586 (2018-11-21)
To date, blue dual fluorescence emission (DFE) has not been realized because of the limited choice of chemical moieties and severe geometric deformation of the DFE emitters leading to strong intramolecular charge transfer (ICT) with a large Stokes shift in

Aromatic-imide-based thermally activated delayed fluorescent (TADF) enantiomers, (+)-(S,S)-CAI-Cz and (-)-(R,R)-CAI-Cz, were efficiently synthesized by introducing a chiral 1,2-diaminocyclohexane to the achiral TADF unit. The TADF enantiomers exhibited high PLQYs of up to 98 %, small ΔEST  values of 0.06 eV, as well
