    摘要: The invention provides a sensor for detecting nitrogen containing high explosives. The sensor includes a substrate and a blue-photoluminescent metallofluorene copolymer to be carried on said substrate during testing for nitrogen containing high explosives. The copolymer is preferably a blue-photoluminescent metallofluorene copolymer, and preferably is a vinyl bridged silafluorene copolymer. A method for detecting nitrogen containing high explosives involves exposing a copolymer to an analyte, preferably by spraying the copolymer or otherwise coating the substrate after it has been exposed to analyte and then exciting the copolymer to luminesce. The copolymer is observed for fluorescence quenching, which can be through human or electronic observation. The invention also provides for synthesis of a vinyl bridged silafluorene polymer by providing diethynylmetallofluorene and dihydrosilafluorene as precursors and conducting catalytic hydrosilation of the precursors. In a blue emitting organic light emitting diode of the invention, an emitting layer is blue-photoluminescent metallofluorene copolymer.

    摘要: A method of the invention is a method of detecting nitramines and nitrate esters believed to be present on a sampling substrate. In the method, a sampling substrate is exposed to a first reagent that is formulated to react with nitramine- and nitrate ester-type explosives to release nitrite. The sampling substrate is then exposed to a second reagent that contains an acid to react with the nitrite and a diaminoaromatic present in either the first or second reagent, to form a triazole that will luminesce. Another method of the invention combines this process for nitramine- and nitrate ester-based explosives detection with a technique to detect nitroaromatic-based explosives using luminescent polymers, for a three-step process for the detection of explosives in these three classes.
