Patent number: 8198096Abstract: 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 ?-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 such as heterocycles, phosphate ester groups and in particular explosives and chemical warfare agents in a gaseous state.Type: GrantFiled: September 29, 2006Date of Patent: June 12, 2012Assignee: Massachusetts Institute of TechnologyInventors: Timothy M.
