LINEAR CHEMOSELECTIVE POLYSILOXANES FOR CHEMICAL SENSOR APPLICATIONS

摘要

This invention generally relates to a new class of chemoselective polymer materials. In particular, the invention relates to linear polysiloxane compounds for use in various analytical applications involving sorbent polymer materials, including chromatography, chemical trapping, analyte collection, and chemical sensor applications. These polymers have pendant and terminal aryl, alkyl, alkenyl, and alkynyl groups that are functionalized with halogen substituted alcohol or halogen substituted phenol groups. These polymeric materials are primarily designed to sorb hydrogen bond basic analytes such as organophosphonate esters (nerve agents and precurcors) and nitro-substituted compounds (explosives).
