Abstract:

Pyrene-containing water-soluble probes for the fluorescent detection of nitroaromatic compounds (NACs), such as explosive components (2,4-DNT and 2,4,6-TNT) and herbicides (2,4-dinitrocresol, 2,4-DNOC), in aqueous media are reported. In the probes, the introduction of surface-active hydrophilic heads at the periphery of lipophilic (i.e., hydrophobic) pyrene tails resulted in the formation of highly fluorescent micelle-like aggregates/pre-associates in aqueous solutions at concentrations of 10(-5)m. The enhanced fluorescence quenching of the herein reported architectures is achieved in the presence of ultra-trace amounts of TNT or 2,4-DNT with values of Stern-Volmer quenching constant close to 1x10(5)m(-1) and a detection limit as low as 182ppb. The most hydrophilic probes demonstrated higher response to 2,4-DNT over TNT. Filter paper test strips impregnated with 1x10(-5)m solutions of the probes were able to detect TNT, 2,4-DNT, and other NACs at levels as low as 50ppb in water.
