The present invention relates to a class of luminescent and conductive polymer compositions having chromophores, and particularly solid films of these compositions exhibiting increased luminescent lifetimes, quantum yields and amplified emissions. These desirable properties can be provided through polymers having rigid groups designed to prevent polymer reorganization, aggregation or &pgr;-stacking upon solidification. These polymers can also display an unusually high stability with respect to solvent and heat exposures. The invention also relates to a sensor and a method for sensing an analyte through the luminescent and conductive properties of these polymers. Analytes can be sensed by activation of a chromophore at a polymer surface. Analytes include aromatics, phosphate ester groups and in particular explosives and chemical warfare agents in a gaseous state. The present invention also relates to devices and methods for amplifying emissions by incorporating a polymer having an energy migration pathway and/or providing the polymer as a block co-polymer or as a multi-layer.
本发明涉及一类具有色团的发光和导电聚合物组合物,特别是这些组合物的固体薄膜表现出增加的发光寿命、量子产率和放大的发射。通过具有刚性基团的聚合物,可以提供这些理想的性质,以防止聚合物在固化时重新组织、聚集或π-堆积。这些聚合物还可以显示出相对于溶剂和热暴露的异常高稳定性。本发明还涉及一种通过这些聚合物的发光和导电性质来感测分析物的传感器和方法。通过在聚合物表面激活色团,可以感测分析物。分析物包括芳香族、
磷酸酯基团和特别是气态炸药和
化学战剂。本发明还涉及通过将具有能量迁移通路的聚合物并入或将聚合物作为块共聚物或多层的装置和方法来放大发射。
