    Abstract: The present invention generally relates to polymers with lasing characteristics that allow the polymers to be useful in detecting analytes. In one aspect, the polymer, upon an interaction with an analyte, may exhibit a change in a lasing characteristic that can be determined in some fashion. For example, interaction of an analyte with the polymer may affect the ability of the polymer to reach an excited state that allows stimulated emission of photons to occur, which may be determined, thereby determining the analyte. In another aspect, the polymer, upon interaction with an analyte, may exhibit a change in stimulated emission that is at least 10 times greater with respect to a change in the spontaneous emission of the polymer upon interaction with the analyte. The polymer may be a conjugated polymer in some cases. In one set of embodiments, the polymer includes one or more hydrocarbon side chains, which may be parallel to the polymer backbone in some instances. In another set of embodiments, the polymer may include one or more pendant aromatic rings. In yet another set of embodiments, the polymer may be substantially encapsulated in a hydrocarbon. In still another set of embodiments, the polymer may be substantially resistant to photobleaching. In certain aspects, the polymer may be useful in the detection of explosive agents, such as 2,4,6-trinitrotoluene (TNT) and 2,4-dinitrotoluene (DNT).

    Abstract translation: 本发明一般涉及具有允许聚合物用于检测分析物的激光特性的聚合物。 在一个方面，聚合物在与分析物相互作用时可以表现出可以以某种方式确定的激光特性的变化。 例如，分析物与聚合物的相互作用可能影响聚合物达到允许发生光子的受激发射的激发态的能力，这可以被确定，从而确定分析物。 在另一方面，聚合物在与分析物相互作用时可能表现出相对于与分析物相互作用时聚合物自发发射变化的至少10倍的受激发射的变化。 在某些情况下，聚合物可以是共轭聚合物。 在一组实施方案中，聚合物包括一个或多个烃侧链，其在一些情况下可以平行于聚合物主链。 在另一组实施方案中，聚合物可以包括一个或多个芳族环。 在又一组实施方案中，聚合物可以基本上包封在烃中。 在又一组实施方案中，聚合物可以基本上抵抗光漂白。 在某些方面，聚合物可用于检测爆炸剂，例如2,4,6-三硝基甲苯（TNT）和2,4-二硝基甲苯（DNT）。
