Fig. 1: Molecular design strategy.

Schematic illustration of hybridization of short- and long-range charge transfer excited state applied to 2,5-tDPAtDIDCz (right). The electronic structure of tDIDCz (left) is reorganized by adopting bis(4-(tert-butyl)phenyl)amine units. The blue/red colored parts are HOMO/LUMO distribution of corresponding molecules, respectively.
