摘要：

A simple thiophene based fluorescent probe 1 was prepared for the detection of Ag+ in aqueous solution. Probe 1 exhibits high selectivity and sensitivity toward Ag+ as fluorescence "off-on" behavior in HEPES buffered MeOH-H2O (1:1, (v/v) HEPES = 50 mM, pH = 7.4) solution. The detection limit was calculated to be 1.28 x 10 -7 M with an association constant of 1.58 x 10(6) M-1 by fluorescence titration experiments. The probe was also demonstrated to detect Ag+ in real samples and in living cells.
