Abstract

A chiral chromophore with thermally activated delayed fluorescence characteristics is designed. A model describing vibrations of the dihedral angle between donor and acceptor units allowed at room temperature explains the enhanced fluorescence rate of the molecule, including a nearly 100% photoluminescence quantum yield and the absence of circularly polarized emission characteristics from enantiomers of the chromophore.
