title: Enhanced electroluminescence efficiency in a spiro-acridine derivative through thermally activated delayed fluorescence.
abstract: Make your OLED fluorescent: an aromatic molecule based on a spiro-acridine derivative was designed, and its photoluminescence and electroluminescence were characterized. By combining the donor and acceptor moieties a small energy gap between the lowest singlet and triplet states was achieved. This design leads to an organic light-emitting diode (OLED) that rivals phosphorescent devices regarding exciton generation efficiency.
