    A novel B,O,N-doped mesogen with narrowband MR-TADF emission
    (2024) Knöller, Julius A.; Sönmez, Burcu; Matulaitis, Tomas; Gupta, Abhishek Kumar; Zysman-Colman, Eli; Laschat, Sabine
    Modification of an unsymmetric B,O,N-doped aromatic core with peripheral mesogenic units triggers self-assembly into a columnar hexagonal mesophase, which is stable between 22 and 144 °C. The columnar assembly is preserved in a glassy state below 22 °C. The B,O,N-doped mesogen displays narrowband sky-blue multiresonance thermally activated delayed fluorescence (MR-TADF) under diluted conditions and bright excimer emission in condensed phase. Our combined experimental and theoretical approach provides insight into the development of strongly aggregating liquid crystalline MR-TADF emitters.
