ABSTRACT:
The subject invention pertains to a method and apparatus for sensing nitroaromatics. The subject invention can utilize luminescent, for example fluorescent and/or electroluminescent, aryl substituted polyacetylenes and/or other substituted polyacetylenes which are luminescent for sensing nitroaromatics. In a specific embodiment, the subject invention can utilize thin films of fluorescent and/or electroluminescent aryl substituted polyacetylenes and/or other substituted polyacetylenes which are fluorescent and/or electroluminescent. In a specific embodiment, the fluorescence from thin films of fluorescent, substituted polyacetylene, such as—poly-[1-phenyl-2-(4-trimethylsilylphenyl)ethyne] (PTMSDPA) is strongly quenched by the vapors of a variety of nitroaromatic compounds present at levels ranging from parts-per-million to parts-per-billion in air.
