Abstract
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.
