Design of a highly sensitive and selective bulk optode based on fluorescence enhancement of N,N′-bis-(1-hydroxyphenylimine)2,2′-pyridil Schiff base: Monitoring of zinc(II) ion in real samples and DFT calculation

- Preparing a new recognition component for optode.
- Applying the constructed optode for determination of Zn2+ ions in real samples.
- Enhancing the sensitivity, selectivity and response time of the optode.
- Theoretical calculations were employed to support the sensing mechanism of the sensor toward Zn2+.
