The selective responding of Salen-type fluorescent probe
N
N'-bis(2-hydroxy-1- naphthaldehyde)-l
2-phenylenediimine(NAPPDIH) to Mg
2+
was studied. The fluorescence and UV/Vis titration experiments indicated that NAPPDIH bound Mg
2+
at the molar ratio of 1:1. With the binding of NAPPDIH to Mg
2+
the fluorescence spectra exhibited a specific enhancement
the UV-Vis absorption exhibited a red shift
and a naked eye color varied from pale yellow to deep yellow. The influence of other metal cations on the fluorescent spectra of NAPPDIH was investigated
the results showed that the fluorescence intensity of NAPPDIH could be greatly increased only by Mg
2+
ion. Besides
a good linearity between the enhanced fluorescence intensity and the concentration of Mg
2+
from 3.0?10

mol/L to 5.0?10

mol/L was established. NAPPDIH was predicted as a fluorescent probe to rapidly detect Mg
