摘要

A simple quinoline-based derivative (AQDPA) was developed as a highly efficient fluorescent sensor for sensing Zn2+ and sequential recognition of pyrophosphate and sulfur ions. This chemosensor was synthesized from diisopropylamine and 2-chloro-N-(quinolin-8-yl)acetamide. The non-fluorescence sensor displayed significant and specific fluorescence enhancement after binding to Zn2+ with high selectivity. The fluorescence titration analysis shows a detection limit for Zn2+ at 4.1 x 10(-8) M. The sensing mechanisms of AQDPA binding to Zn2+ were supported by H-1 NMR, HR-MS analysis, and density functional theory (DFT) study. Moreover, the fluorescence imaging in HeLa cells suggested that this simple sensor had great potential in the application of biological imaging.
