| Summary: | Two acid hydrazones incorporating xanthene as a metal chelating centre (
B-XAN
and
N-XAN
) have been synthesized, characterized and evaluated for the optical sensing of Mg
2+
and Al
3+
. The replacement of the naphthyl moiety in
N-XAN
by the phenyl moiety in
B-XAN
leads to total specificity of the latter one towards Mg
2+
. The
B-XAN
exhibited a highly sensitive and selective 'turn-on' fluorescent response towards Mg
2+
through intense blue fluorescence enhancement. This measurement was free from any interference by other cationic analytes including the Ca
2+
and Al
3+
also. The binding constant, stoichiometry as well as the mechanistic aspect of the above sensing phenomenon were also studied through various spectroscopic methods.
