Azaneylylidene-based tetradentate Schiff base as a new “ON-OFF” fluorescent probe for the detection of Cu(II) ion: Synthesis, characterization and real sample analysis

Highly selective and sensitive fluorescent “TURN-ON” furan-based Schiff base for zinc(ii) ion probing: chemical synthesis, DFT studies, and X-ray crystal structure

“…Additionally, zinc (Zn 2+ ) increases the production of amyloid and inhibits apoptosis, which are both hypothesized to be connected to the etiology of Alzheimer's disease. [21][22][23][24][25] However, high concentrations of Zn 2+ ions in humans are linked to neurodegenerative disorders. In this regards, it is very much essential to design and develop chemical sensors that are sensitive and selective to Zn 2+ ions.…”
