reaction. Compared with control compound 1, the obtained target compound (RBGlc-3) could be independently applied for the detection of Hg(2+) in water medium, and not disturbed by Ce(3+), Eu(3+), Ca(2+), Cd(2+), Fe(2+), Ba(2+), Co(2+), Cu(2+), Zn(2+), Pb(2+), Mg(2+), Ni(2+), K(+), Ag(+), Na(+), NH4(+), CH3COO(-), S2O4(2-), SO4(2-), SO3(2-) and Cl(-). 1:1 Stoichiometry is the most likely recognition
