title: Charge transfer based "turn-on" chemosensor for Zn²⁺ ion recognition using new triaryl pyrazoline derivative.
abstract: The fluoroionophore PY serves as a selective and fluorimetric chemosensor for Zn(2+) based on charge transfer (CT). A mechanism for the binding mode was proposed based on fluorescence changes, NMR experiments and theoretical calculations. The 1:1 stoichiometry between Zn(2+) and the sensor was deduced from Job's plot. The addition of EDTA quenches the fluorescence of PY.Zn(2+) complex offers PY as a reversible chemosensor.
