Embedding a boroxazine (B3N2O) heterocycle by a m-quinquephenyl scaffold renders a B/N/O substituted nanographene molecule. The target compound can be synthesized in four steps and in good overall yield. The incorporation of a boroxazine core modifies the electronic structure and results in high fluorescence quantum yield.
