Highly Sorbent Films Derived from Ni(SCN)(2)(4-picoline)(4) for the Detection of Chlorinated and Aromatic Hydrocarbons with Quartz Crystal Microbalance Sensors.


A quartz crystal microbalance (QCM) spray-coated with a Ni(SCN)(2)(4-picoline)(4) film is a sensitive detector for small aromatic (benzene, toluene) and chlorinated (trichloroethylene, perchloroethylene) vapors with a planar molecular geometry. Frequency changes during transient exposures to these vapors are rapid and reversible. In contrast, frequency… (More)
