A 1,2,3-trioctyloxyphenyl-based organogel (G1) containing a pyrene fluorophore and urea-sulfonamide anion binding sites was designed and synthesized. Gelator G1 can form stable organogels with dramatic aggregation-induced emission (AIE) in some organic solvents. The self-assemble mechanism of G1 was investigated by concentration depended 1H NMR, XRD, FT-IR and SEM techniques. In addition, G1 shows...
A new pyrenyl-appended triazole for fluorescent sensing of Hg 2+ , 1, has been synthesized and characterized. Upon addition of Hg 2+ to 1 in the acetonitrile aqueous solution, more than 80% of the initial fluorescence intensity of 1 was quenched, which allowed a selective and sensitive fluorescent detection of Hg(II) without any interference from other metal ions. 1 H NMR analysis...
