Linear Chemoselective Carbosilane Polymers and Methods for Use in Analytical and Purification Applications

Linear polycarbosilane compounds for use in analytical applications involving sorbent polymer materials, including chromatoghraphy, chemical trapping, analyte collections, and chemical sensor applications. These polymers have pendant and terminal aryl, alkyl, alkenyl, and alkynyl groups that are funcionalized with halogen substituted alcohol or phenol groups, having the general structure: wherein n is an integer greater than 1; at least one R1 and R2 is a linear or branched arm having at least one group independently selected from alkyl, alkenyl, alkynyl, and aryl groups, and having at least one halogen substituted alcohol or phenol groups attached thereto; X is a polymer component comprising alkylene, alkenylene, alkynylene, or arylene groups; and Z1 and Z2 are end groups independently selected from alkyl, alkenyl, alkynyl, aryl, alkyl silanes, aryl silanes, hydroxyl, silicon hydride, alkoxides, phenols, halogen substituted alcohols, halogen substituted phenols, and organosilyl.
