Dihydrodiboraheptacene and dihydrodiboranonacene, the hitherto longest boron-embedded heteroacenes, have been successfully synthesized. Both compounds exhibit highly efficient anti-Kasha emissions through the thermal population mechanism, and the photoluminescence quantum yield (PLQY) of dihydrodiboraheptacene is as high as 98±2 %. This work provides new opportunities for the development of novel boraacene-based
