A Readily-Synthesized Fluorescent Probe Based on N, N-Bis (Pyridin-2-Ylmethyl) Aniline for Copper(II) Detection in Aqueous Solution.
In this paper, probe 1 based on N, N-bis (pyridin-2-ylmethyl) aniline is prepared as an effective fluorescent probe for Cu2+. It exhibits good sensitivity and selectivity for Cu2+over other metal ions in aqueous solution. The detection limit of probe 1 is 56 nM. Furthermore, probe 1 is pH-insensitive under near-neutral conditions and can work well in environmental samples.
