【 摘 要 】

A quinoline-thiooxorhodamine conjugate fluorescent sensor (1) has been synthesized. Sensor 1 exhibits high selectivity and sensitivity to Hg2+ in H2O/DMSO (95/5, v/v, HEPES 20 mM, pH = 7.4) solution with fluorescence detection. Other tested metal ions do not induce any significant fluorescence intensity changes. Sensor 1 interacts with Hg2+ through a 1:1 binding stoichiometry with a good anti-inference ability. In addition, fluorescent imaging of Hg2+ in Hela cells is also successfully demonstrated.
