文摘

•: We synthesized two new probers which have similar structures, however their optical properties are very great differences.
•: The structure of the sensor L1 is original for the detection of pH and Fe³⁺ simultaneously.
•: A new structure formed from compound L2 upon acidification and result in the generation of the isosbestic point.
•: We have proved the structure change of L2 upon acidification by absorption spectra, ¹H NMR and DFT/TDDFT calculation.
