blue-emitting black phosphorus quantum dots
(BPQDs) is based on the liquid-phase exfoliation of bulk BP. We report
the synthesis of soluble BPQDs showing a strong visible blue-light
emission. Highly fluorescent (photoluminescence quantum yield of ≈5%
with the maximum emission (λmax) at ≈437 nm)
and dispersible BPQDs in various organic solvents are first prepared
by simple ultrasonication of BP crystals in chloroform in the ambient
atmosphere. Furthermore, simple mussel-inspired surface functionalization
of BPQDs with catechol-grafted poly(ethylene glycol) in basic buffer
afforded water-soluble blue-emitting BPQDs showing long-term fluorescence
stability, very low cytotoxicity, and excellent fluorescence live
cell imaging capability.
