Puntos clave

The research aims to develop a fluorescent chemosensor for Al³⁺ ions.
Synthesis of schiff-base tert-butyl (Z)-2-((2-hydroxynaphthalen-1-yl)methylene)hydrazine-1-carboxylate (KH) via condensation reaction.
KH's efficiency as a fluorescent chemosensor for Al³⁺ ions was tested.
The synthesized compound KH effectively responds to Al³⁺ ions.
ESIPT suppression induces a turn-on fluorescent response.

Resumen

The Schiff-base tert-butyl (Z)-2-((2-hydroxynaphthalen-1-yl)methylene)hydrazine-1-carboxylate (KH) was synthesized via a condensation reaction between tert-butyl carbazate and 2-hydroxy-1-naphthaldehyde in methanol. The compound KH functions as an efficient fluorescent chemosensor for Al3+ ions,...
