摘要
A new chemosensor for Cu(2+) was synthesized based on 1,2,3,4,5,6,7,8,9,10-decahydroacridine-1,8-dione dyes, which exhibited an obvious fluorescent selectivity to the sensing of Cu(2+) ions over other cations, such as Na(+), K(+), Ca(2+), Cd(2+), Co(2+), Hg(2+), Mg(2+), Mn(2+), Ni(2+), Zn(2+), Ag(+) and Pb(2+). Moreover, it presented a fluorescent switch function when EDTA was added to the compound-Cu(2+) complex in examined systems.
