An azaindole-hydrazine imine moiety as sensitive dual cation chemosensor depending on surface plasmon resonance and emission properties

- Novel azaindole-based colorimetric and fluorescent sensor with an attached hydrazine group.
- Dual function of azaindole derivative L favoring reduction of silver ions and their stabilization as nanoparticles.
- Naked eye detection of Ag+ ions through color change of solution from colorless to yellow.
- Selective sensing of Fe2+ ions using quenched emission response.
- Logic circuit operating with incorporation of AND and OR logic gate.
