Area of Science:

• Analytical Chemistry
• Materials Science
• Organic Chemistry

Background:

• Metal ion detection is crucial in environmental monitoring and biological systems.
• Chalcones are versatile organic compounds with potential applications in sensing.
• Thiophene derivatives offer unique electronic properties for chemosensor development.

Purpose of the Study:

• To synthesize and characterize a novel bis thiophene-based chalcone.
• To evaluate the chemosensor's selectivity and sensitivity for detecting ferric ions (Fe3+).
• To explore the potential application of this chalcone in detecting Fe3+ in a specific solvent mixture.

Main Methods:

• Synthesis of the bis thiophene-based chalcone.
• Spectroscopic analysis (UV-Vis, Fluorescence) to study the interaction with metal ions.
• Testing selectivity against various competing metal ions.
• Determination of the limit of detection (LOD) in a DMF:H2O (9:1) solution.

Main Results:

• The synthesized chalcone exhibited high selectivity towards Fe3+ ions.
• The chemosensor showed a distinct response in the presence of Fe3+.
• A low detection limit in the micromolar range was achieved for Fe3+ detection.
• The sensor maintained selectivity in a mixed solvent system (DMF:H2O, 9:1).

Conclusions:

• The bis thiophene-based chalcone is a highly selective and sensitive chemosensor for Fe3+ detection.
• This sensor offers a promising tool for the selective determination of ferric ions in relevant media.
• The findings contribute to the development of advanced chemosensors for metal ion analysis.
