    • 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.
    • 本发明提供了一种用于检测含氮高爆炸药的传感器。 该传感器包括衬底和在测试含氮高爆炸物时在所述衬底上携带的蓝光致发光金属芴共聚物。 该共聚物优选为蓝光致发光金属芴共聚物,并且优选为乙烯基桥联的硅杂芴共聚物。 用于检测含氮高爆炸药的方法涉及将共聚物暴露于分析物,优选通过喷雾共聚物或以其他方式涂覆衬底,之后将衬底暴露于分析物,然后激发共聚物发光。 观察共聚物的荧光猝灭,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硅烷芴作为前体并且进行前体的催化氢化硅烷化来合成乙烯基桥联的硅杂芴聚合物。 在本发明的蓝色发光有机发光二极管中,发光层是蓝光发光的金属芴共聚物。

    • Monovinyl aromatic polymer compositions with high melt strength, good flow and good heat properties which are suitable for fast injection molding, blow molding and thermoforming applications, comprising non-linear monovinyl aromatic polymers and copolymers having comb-type structures with 3 branches, star type structures with 4 to 6 branches, and/or dendritic structures in which the branches themselves have attached branched units. These compositions possess inherent melt strength and can be blow molded or thermoformed without sagging or molded into articles in shorter cycle times using less material than linear monovinyl aromatic polymers and copolymers with the same flow and heat distortion temperatures. Also dislosed is a process for making high molecular weight branched monovinyl aromatic polymers, for example, Mw between 75,000 and 500,000, at high rates, comprising polymerizing pure styrene monomer or styrene monomer and polymerizable comonomer via a continuous free radial polymerization process using a peroxide initiator, for example, n-butyl tert-butyl peroxy fumarate, selected from a new class of vinyl peroxide initiators that contain both a copolymerizable double bond and an organic peroxide moiety.
