Bispyrenylalkane Chemosensor for the Naked-eye Detection of Nitro-explosives

Bispyrenylalkane Chemosensor for the Naked-eye Detection of Nitro-explosives

Pyrene-based compounds have a great potential as fluorescent chemosensors for various analytes including common nitro-explosives, such as 2,4,6-trinitrotoluene (TNT). Compounds having two pyrene units in one molecule, such as bispyrenylalkanes, are able to form stable, bright emissive in a visual wa...
