| 摘 要： | A novel chemosensor 1 （CS1） bearing one coumarin and two carbodithioate groups was synthesized and its fluorescent sensing behavior toward metal ions was investigated. Ag^＋ addition to a CH3COCH3/H2O （3：7, v：v） solution of CS1 gave a significantly quenched fluorescence. Other ions including Pb^2＋, Zn^2＋, Cu^2＋, Ca^2＋, Cd^2＋, Co^2＋, Mg^2＋, Mn^2＋, Hg^2＋, Ag^＋, Ni^2＋ induced no or much smaller spectral changes. This constitutes an ON-OFF Ag^＋-selective fluorescent chemosensor.

| Abstract: | A novel chemosensor 1 (CS1) bearing one coumarin and two carbodithioate groups was synthesized and its fluorescent sensing behavior toward metal ions was investigated. Ag addition to a CH3COCH3/H20 (3:7, v:v) solution of CS1 gave a significantly quenched fluorescence. Other ions including Pb2 , Zn2 , Cu2 , Ca2 , Cd2 , Co2 , Mg2 , Mn2 , Hg2 , Ag , Ni2 induced no or much smaller spectral changes. This constitutes an ON-OFF Ag -selective fluorescent chemosensor. |
