A fluorescence-based sensor can comprise a nanofiber mass of nanofibers having tubular morphology and a fluorescence detector, where fluorescence of the nanofibers decreases upon contact with a nitro-containing compound. The nanofibers can comprise carbazole-cornered, arylene-ethynylene tetracyclic macromolecules of formula I: where R1-R4 are alkyl-containing groups. The tubular morphology allows for highly selective detection of trinitrotoluene over other nitro-based compounds and oxidizing organic compounds.
