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.
本发明涉及强氢键酸性吸附剂。该吸附剂可以以一种形式提供,该形式限制或消除氢键酸性位点在相邻吸附剂分子之间的分子内键合,例如,通过在氢键酸性位点旁边提供立体阻碍基团。氢键位点可以是基于双
酚体系结构的
酚结构。本发明的吸附剂可以用于捕获或检测危险
化学品或爆炸物的方法中。
