An ESIPT blocked highly ICT based molecular probe to sense Zn (II) ion through turn on optical response: Experimental and theoretical studies

A pyrene-induced PET-based chemosensor for biologically important Zn(ii) ions: application in test strips and live cell imaging studies

“…The Benesi–Hildebrand fitting equation 51 was used to evaluate the association constant ( K a ) for DTQ towards Zn( ii ) by plotting ( F max. − F min.…”

“…Then, cover slips were observed under BX42 fluorescence microscopy, and the images were recorded. 51…”

An overview of Schiff base-based fluorescent turn-on probes: a potential candidate for tracking live cell imaging of biologically active metal ions

“…Gudasi and colleagues developed a simple and inexpensive optical sensor ( probe- 35 ) 95 via a condensation reaction between 2-hydroxy-1-naphthaldehyde and 5-di- tert -butyl-2-hydroxybenzohydrazide in MeOH in 2020. The pure form of probe- 35 exhibited very poor emission, and with the increase in the concentration of Zn( ii ) ions, the fluorescence intensity was increased by 17-fold and a 60 nm blue shift in the emission maxima was observed, which turned the colorless solution into a vivid yellow solution in 20% aqueous acetonitrile.…”
