We present a reaction-based fluorescent probe (1) for Hg2+ and CH3Hg+, based on the displacement reaction of the arylboronic acid with the mercury species. 1 showed promising sensing properties for Hg2+ and CH3Hg+, such as high selectivity and sensitivity, turn-on response, fast response to Hg2+ (3Hg+ (5 min), low detection limits and operation in purely aqueous solutions.

The (bis)dansylated sulfonamide 1,2-C6H4(NHSO2C10H6-5-N(CH3)2)2 (1) extracted Pb(II) selectively from water into 1,2-dichloroethane via an ion-exchange mechanism and showed fluorescence quenching upon Pb(II) extraction. The distribution ratios for metal extraction (determined by ICP-MS) for Pb(II) were 133-1410 times higher than those for other metal cations [Co(II), Ni(II), Cu(II), Zn(II), and Cd(II)] under identical conditions. Fluorescence quenching was observed upon Pb(II) extraction, which was dependent on Pb(II) concentration. The monodansylated control, C6H5NHSO2C10H6-5-N(CH3)2(2), showed neither extraction nor quenching, indicating that the fluorescence effects are a direct result of Pb coordination to 1. The observed selectivity for Pb(II) is ascribed to the formation of a low-coordinate binary Pb(II)-Sulfonamido complex in the organic phase. Copyright

A novel compound, (5-(dimethylamino)-N-(4-ethynylphenyl)-1- naphthalenesulfonamide), was prepared and characterized; it shows dual functional roles as an effective antitumor and a two-photon induced bio-imaging agent.
Fluorescence modulation in anion sensing by introducing intramolecular H-bonding interactions in host-guest adducts

, p. 186 - 188 (2008/02/08)
Fluorescence signaling in anion binding is modulated from quenching to enhancement by intramolecular H-bonding stabilization of anion-ionophore adducts; the intramolecular H-bonding is suggested to suppress the quenching processes otherwise possible and i
