Abstract

Abstract Phosphonic acids, phosphonate esters and cyclohexylammonium phosphonates, spray-coated onto surface acoustic wave (SAW) devices, were exposed to vapors of chloroethyl ethyl sulfide (CEES), dimethyl methylphosphonate (DMMP), and water. Changes in the resonance frequency of the device or the resistance of the coating were collected by computer-controlled data acquisition. Two of the esters showed major reversible and selective response to CEES, and one of the acids showed similar behavior with DMMP.
