Carbosilane polymers and methods for use in analytical and purification reactions

This invention relates generally to a new class of chemoselective polymer materials. 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: wherein n is an integer greater than 1; wherein at least one of R1 and R2 is a pendant group having at least one aryl group independently selected from the group consisting of a phenol, a halogen substituted phenol, and an aryl hydrocarbon with a halogen substituted alcohol substitutent, or combinations thereof; wherein any said R1 and R2 aryl groups are attached to said [Si—X—]n either directly or through a short hydrocarbon...
