A glycosyl-rhodamine fluorescent probe with good water-solubility has been designed and synthesized through click reaction. Compared with control compound 1, the obtained target compound (RBGlc-3) could be independently applied for the detection of Hg2+ in water medium, and not disturbed by Ce3+, Eu3+, Ca2+, Cd2+, Fe2+, Ba2+, Co2+, Cu2+, Zn2+, Pb2+, Mg2+, Ni2+, K+, Ag+, Na+, NH4+, CH3COO-, S2O42-, SO42-, SO32 and Cl-. 1:1 Stoichiometry is the most likely recognition mode of RBGlc-3 toward Hg2+ ion, and the OFF-ON fluorescent mechanism of RBGlc-3 is proposed.
