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.
