Area of Science:

Analytical Chemistry
Inorganic Chemistry
Chemical Sensing

Background:

Sulfide ions (S^2-) are crucial in biological processes but require sensitive detection methods.
Existing detection methods for sulfide can be complex or lack selectivity.
Development of novel chemosensors is needed for efficient sulfide detection.

Purpose of the Study:

To synthesize and characterize a salamo-based copper(II) complex probe (L-Cu²⁺).
To evaluate the probe's efficacy in detecting sulfide ions (S^2-) with high sensitivity and selectivity.
To explore the probe's potential for visual detection of sulfide and hydrogen sulfide (H₂S).

Main Methods:

Synthesis of a salamo-based copper(II) complex probe (L-Cu²⁺).
Spectroscopic analysis including UV-Vis absorption and fluorescence spectroscopy.
Testing selectivity against various interfering anions.
Visual colorimetric detection and H₂S gas sensing experiments.

Main Results:

The L-Cu²⁺ probe exhibited a strong fluorescence response upon interaction with sulfide ions (S^2-).
High sensitivity and selectivity for S^2- detection were confirmed, even in the presence of other anions.
A visible color change from colorless to bright yellow occurred upon S^2- addition.
The probe successfully detected S^2- in H₂S gas molecules.

Conclusions:

The developed L-Cu²⁺ probe is effective for sensitive and selective sulfide detection.
The probe allows for naked-eye detection of sulfide ions via a colorimetric response.
This probe holds significant potential for applications in biological and medical diagnostics.
