The novel nitrogen-doped carbon quantum dots (N-CQDs) with high fluorescence quantum yield of 23.2% were successfully prepared via a simple hydrothermal reaction with citric acid and 2,2′ -dipicolylamine. The as-prepared blue fluorescent N-CQDs had excellent water dispersibility, and showed pH and excitation-dependent emission behaviors. Noticeably, owing to the strong interaction between the residual 2,2′ -dipicolylamine group on the surface of N-CQDs and Fe3+, the N-CQDs could be used as a turn off fluorescence probe for Fe3+ sensing through an electron transfer process. Moreover, the photoluminescent N-CQDs/poly(vinyl alc.) film was further applied for latent fingermark imaging. In the experiment, the researchers used many compounds, for example, Bis(pyridin-2-ylmethyl)amine(cas: 1539-42-0Related Products of 1539-42-0)
Bis(pyridin-2-ylmethyl)amine(cas: 1539-42-0) is a secondary amine with two picolyl substituents. As a tridentate ligand this compound provides three nitrogen donors that affords good selectivity for Zn2+ over biologically relevant metals such as Na+, K+, Mg2+ and Ca2+, and leaves coordination sites free for anion binding.
