A new fluorescent sensor detects zinc ions using internal charge transfer. Upon binding, the sensor exhibits a distinct color change, enabling sensitive and selective zinc detection.

Area of Science:

  • Analytical Chemistry
  • Materials Science

Background:

  • Fluorescent chemosensors are crucial for detecting metal ions.
  • Internal charge transfer (ICT) mechanisms offer tunable photophysical properties.

Purpose of the Study:

  • To design and synthesize a novel ratiometric fluorescent chemosensor (compound 5) for zinc ion detection.
  • To investigate the sensing mechanism based on internal charge transfer (ICT).

Main Methods:

  • Synthesis of the fluorescent chemosensor.
  • Spectroscopic analysis (absorption and emission) in acetonitrile.
  • Investigation of the metal-ligand complex formation upon zinc ion addition.

Main Results:

  • The chemosensor exhibits absorption and emission in the visible range.

  • A 1:2 metal/ligand complex formation results in emission changes at 616 nm and 672 nm.

    • Conclusions:

    • The developed sensor demonstrates ratiometric fluorescent sensing capabilities for zinc ions.
    • The ICT mechanism facilitates a distinct spectral response upon zinc binding.
    • The sensor shows potential for sensitive and selective zinc ion detection.
