    • 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.
    • 本发明提供一种用于检测含有高爆炸物的氮的传感器。 传感器包括在测试含氮高爆炸物的测试期间在所述基板上承载的基底和蓝色光致发光金属芴共聚物。 共聚物优选为蓝色光致发光金属芴共聚物,优选为乙烯基桥接的硅芴共聚物。 用于检测含氮高爆炸物的氮的方法包括将共聚物暴露于分析物,优选通过喷雾共聚物或以其它方式在暴露于分析物之后涂覆基底,然后激发共聚物发光而使共聚物暴露于分析物。 观察到共聚物用于荧光猝灭,其可以通过人或电子观察。 本发明还提供了通过提供二乙炔基金属芴和二氢钐芴作为前体并进行前体的催化硅氢化来合成乙烯基桥接的硅芴聚合物。 在本发明的蓝色发光有机发光二极管中,发光层是蓝光发光金属芴共聚物。
