Abstract
This invention relates generally to a new class of chemoselective polymer materials primarily designed to sorb hydrogen bond basic analytes such as organophosphonate esters (nerve agents and precursors) and nitro-substituted compounds (explosives). In particular, the invention relates to linear polycarbosilane 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 phenol groups, having the general structure:
