Abstract
- A simple quinoline-based derivative (AQDPA) was developed as a highly efficient fluorescent sensor for sensing Zn 2+ 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 Zn 2+ with high selectivity. The fluorescence titration analysis shows a detection limit for Zn 2+ at 4.1 × 10 −8 M. The sensing mechanisms of AQDPA binding to Zn 2+ were supported by 1 H 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. [ABSTRACT FROM AUTHOR]
