Patent number: 8465678Abstract: 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, phosphate ester groups and in particular explosives and chemical warfare agents in a gaseous state.Type: GrantFiled: April 1, 2011Date of Patent: June 18, 2013Assignee: Massachusetts Institute of TechnologyInventors: Timothy M. Swager, Jye-Shane Yang, Vance Williams, Yijun Miao, Claus G. Lugmair, Igor A. Levitsky, Jinsang Kim, Robert Deans
