Abstract
Abstract A highly selective and sensitive acridine-based colorimetric sensor 2-((7-chloro-2-methoxybenzo[b][1,5]naphthyridin-10-yl)amino)phenol (NAP) was developed for detection of Cu2+ ions both in aqueous solution and on test papers. Sensor NAP responses to Cu2+ ions by changing its color from yellow to pink, which could be easily observed by the naked eyes. Furthermore, the mechanism of the binding model of NAP-Cu2+ complex was investigated by 1H NMR, HRMS analysis, and DFT calculations.
