A conjugated polymer was synthesized by the polymerization of 4,7-dibromobenzo[2,1,3]thiadiazole (M-1) with tri{1,4-diethynyl-2,5-bis(2-(2- methoxyethoxy)-ethoxy)}-benzene (M-2) via Pd-catalyzed Sonogashira reaction. The polymer shows strong orange fluorescence. The responsive optical properties of the polymer on various metal ions were investigated through photoluminescence and UV-vis absorption measurements. The polymer displays highly sensitive and selective on-off Hg2+ fluorescence quenching property in tetrahydrofuran solution in comparison with the other cations including Mg 2+, Zn2+, Co2+, Ni2+, Cu 2+, Ag+, Cd2+, and Pb2+. More importantly, the fluorescent color of the polymer sensor disappears after addition of Hg2+, which could be easily detected by naked eyes. The results indicate that this kind of polymer sensor incorporating benzo[2,1,3]thiadiazole moiety as a ligand can be used as a novel colorimetric and fluorometric sensor for Hg2+ detection. 2011 Wiley Periodicals, Inc.

The synthesis of phenylene-ethynylene rods and their use as rigid spacers is described. Alternation of a Sonogashira reaction and silyl group cleavage was used to obtain rigid spacers with even and odd numbers of phenylene units. Preliminary applications of these rods in divalent systems are shown. Inhibition studies with Pseudomonas Aeruginosa lectin LecA showed that the rigid spacer proved greatly beneficial for the inhibitory potency.
