Abstract
The invention relates to strong hydrogen-bond acidic sorbents. The sorbents may be provided in a form that limits or eliminates intramolecular bonding of the hydrogen-bond acidic site between neighboring sorbent molecules, for example, by providing steric groups adjacent to the hydrogen-bond acidic site. The hydrogen bond site may be a phenolic structure based on a bisphenol architecture. The sorbents of the invention may be used in methods for trapping or detecting hazardous chemicals or explosives.
