A Novel Fluorescent Sensor for Fe3+ Based on a Quinoline Derivative
A new fluorescent sensor for detecting Fe<sup>3+</sup> was developed based on chemical modification of the quinoline group. Titration experiments showed that the sensor exhibits high selectivity and sensitivity toward Fe<sup>3+</sup>, even in complex systems. The recognition mechanism was verified through theoretical calculations, demonstrating that the sensor can perform qualitative and quantitative analysis on Fe<sup>3+</sup>. The cell imaging and zebrafish imaging experiments further prove the potential application of the sensor in the field of bioluminescence imaging.
