A new azo-azomethine chemosensor containing active phenolic sites, H2L, has been designed and synthesized for rapid detection of inorganic fluoride over the other anions, such as Clˉ, Brˉ, Iˉ, AcOˉ, H2PO4ˉ, NO3ˉ, N3ˉ in DMSO/water (90/10) media. The 1H NMR titration revealed that the colorimetric response was considered to be the direct consequence of hydrogen-bond formation between phenolic gr...
Pyrene-based compounds have a great potential as fluorescent chemosensors for various analytes including common nitro-explosives, such 2,4,6-trinitrotoluene (TNT). Compounds having two pyrene units in one molecule, bispyrenylalkanes, are able to form stable, bright emissive visual wavelength region excimers both non-polar and polar environments. In this work we wish report that solvents the exc...
