“…The lone pair electron of nitrogen from C]N can be freely transferred to the excited state uorophore, resulting in uorescence quenching. [23][24][25] When the nitrogen and oxygen atoms of FHS-OH coordinate with Al(III), the electron-donating ability decreases, and the PET effect is constrained, leading to a notable enhancement of uorescence emission at 438 nm. [26][27][28][29][30][31][32][33] Besides PET and C]N isomerization could also be involved in the uorescence enhancement.…”

A new chemosensor H 2 L has been designed and synthesized based on an Azo-Schiff base ligand for the selective and sensitive sensing of Co 2+ and Al 3+ ions. The H 2 L as uorescence chemosensor exhibits a linear response toward Al 3+ ions in the concentration range of 1.91 × 10 − 8 M to 4.8 × 10 − 6 M with a limit of detection of 1.91 × 10 − 8 M. The chemosensor also displayed high colorimetric sensitivity for Co 2+ .Fluorescence switch based on the control of EDTA and Al 3+ proved H 2 L could act as a reversible chemosensor. The molecular structure of [NiL] complex has been determined by X-ray crystallography. Author DeclarationsAuthor Contributions Azadbakht and Mostafa Koolivand performed collection of absorption/emission spectra, data analysis, and writing original draft. Naemeh Chidan developed the methodology for synthesis. Saeid Menati synthesized the compounds.

A coumarin‐derived acylhydrazone probe (L) was designed and synthesized for successive detection of Al3+ and H2PO4− in DMSO/H2O solution. The probe L exhibited high selectivity towards Al3+ with visible color change and prominent fluorescence enhancement at 592 nm, while the in situ prepared L‐Al3+ complex could selectively recognize of H2PO4− via fluorescence quenching. The detection limits for Al3+ and H2PO4− were calculated to be 3.4 and 11.0 nM, respectively. The binding ratio of L to Al3+ was obtained as 2 : 1 according to the Job's plot and ESI‐MS while the association constant was determined to be 2.13×104 M−1. Furthermore, the probe L was successfully applied in detection of Al3+ and H2PO4− with test strips and in real water samples.
