Summary
A new rhodamine-based sensor, L, effectively detects iron(III) ions (Fe3+) using colorimetric and fluorescent methods. This sensor demonstrates high selectivity and sensitivity for Fe3+ detection in various solutions.
Area of Science:
- Analytical Chemistry
- Materials Science
Background:
- Rhodamine derivatives are widely used as fluorescent probes.
- Developing selective sensors for metal ions is crucial in environmental and biological monitoring.
Purpose of the Study:
- To develop and investigate a novel rhodamine-based fluorescent sensor, denoted as L.
- To evaluate the sensor's capability for colorimetric and fluorescent detection of iron(III) ions (Fe3+).
Main Methods:
- Synthesis of the rhodamine-based sensor L.
- Spectrophotometric and fluorometric analysis of sensor L in the presence of Fe3+ and other metal ions in dimethyl sulfoxide (DMSO).
Main Results:
- The sensor L exhibited a distinct color change and fluorescence response upon binding with Fe3+.
- Compound L demonstrated high selectivity and sensitivity towards Fe3+ even in the presence of excess competing ions.
- The sensor was effective for iron recognition in potential applications.
Conclusions:
- The novel rhodamine-based sensor L is a promising tool for the selective and sensitive detection of Fe3+.
- Sensor L can be utilized as both a colorimetric and fluorescent probe for iron recognition.
