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 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 mode of RBGlc-3 toward Hg(2+) ion, and the OFF-ON fluorescent mechanism of RBGlc-3 is proposed.
通过点击反应设计并合成了一种具有良好水溶性的糖基罗丹明荧光探针。与对照化合物1相比，所得到的目标化合物（RBGlc-3）可独立用于水介质中Hg(2+)的检测，且不受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-)和Cl(-)的干扰。1:1化学计量比是RBGlc-3对Hg(2+)离子最可能的识别模式，并提出了RBGlc-3的开-关荧光机制。
