A facile, green, and high-output hydrothermal synthesis was proposed for the fabrication of highly fluorescent nitrogen-doped carbon quantum dots (N-doped CDs). The nitrogen content in N-doped CDs reached 19.2% and demonstrated strong blue fluorescence emission was obtained with fluorescence quantum yield (QY) of up to 32.9%, which exhibit high fluorescence quantum yield, high photostability, and excellent biocompatibility. The N-doped CDs possess high photostability, low toxicity, and excellent biocompatibility, based on which the N-doped CDs were successfully applied as a fluorescence probe for cell imaging. Moreover, it was then successfully demonstrated for sensitive and selective detection of Fe3+ in serum.

High Fluorescence Quantum Yield

A dibenzoperylene motif featuring a doubly boron–nitrogen-doped bay region is accessible from an aniline derivative in six steps in good overall yield. Two n-butyl groups provide the BN-doped polycyclic aromatic hydrocarbon with sufficient solubility in common organic solvents. The synthesis sequence allows installation of a second boron atom next to a weakly nucleophilic nitrogen by using a protected boron species. The title compound shows blue fluorescence, an extremely high fluorescence quantum yield, and an interesting doped bay region.
