A Novel Fluorescent Sensor for Fe³⁺ Based on a Quinoline Derivative.

ABSTRACT: A new fluorescent sensor for detecting Fe³⁺ was developed based on chemical modification of the quinoline group. Titration experiments showed that the sensor exhibits high selectivity and sensitivity toward Fe³⁺, even in complex systems. The recognition mechanism was verified through theoretical calculations, demonstrating that the sensor can perform qualitative and quantitative analysis on Fe³⁺. The cell imaging and zebrafish imaging experiments further prove the potential application of the sensor in the field of bioluminescence imaging.
