Abstract

A new naphthol-based chemosensor NPN ((E)-2-(((2-hydroxynaphthalen-1-ylmethylene)amino)isoindoline-1,3-dione) was synthesized. NPN could sense Ga³⁺ by a fluorescence “turn-on” method from colorless to blue. Detection limit for Ga³⁺ by NPN was determined to be 0.26 μM. The sensing mode of NPN and Ga³⁺ turned out to be a 1:1. NPN could also be successfully applied to visible fluorescent test strips. The sensing process of Ga³⁺ by NPN was illustrated through ¹H NMR titration, Job plot, ESI-MS, and DFT calculations.
