A simple Hg2+-selective chemodosimetric system based on thiosemicarbazone was investigated. The transformation of thiosemicarbazone into semicarbazone selectively exerted by Hg2+ ions and the dimerization of semicarbazone resulted in a pronounced OFF-ON-type fluorescent signaling behavior. The coexistent metal ions, such as Fe3+, Ca2+, Cu2+, Co2+, Ni2+, Cd2+, Pb 2+, Zn2+, Cr3+, Mg2+, Na +, K+, and Fe2+, had no obvious interference with the detection of Hg2+. In addition, S12-Hg 2+ plays a high sensitivity for basic anions to form an 'OFF-ON-OFF' type signaling behavior, with the Hg2+-induced emission spectra can be quenched. Moreover, test strips based on S12 exhibited a good selectivity to Hg2+. We believe the test strips could act as a convenient and efficient Hg2+ test kit.

A series of arylthioureas (1), aromatic aldehyde thiosemicarbazones (2) and 5-aryl-2-furfuraldehyde thiosemicarbazones (3) were condensed with 2,4-dichloro-5-fluorophenacyl bromide to yield respective arylaminothiazoles, arylidene/5-aryl-2-furfurylidene hydrazinothiazoles (4). The newly synthesized compounds were characterized by IR, 1H-NMR and mass spectral studies. These compounds were also screened for their antibacterial and anti-inflammatory activities. Two of the newly synthesized compounds showed anti-inflammatory activity comparable with that of Ibuprofen.
