The detection of halogenated hydrocarbons via host–guest chemistry—a mass-sensitive sensor study with QMB- and SAW-devices


  • Financial Support by the “Bundesministerium für Forschung and Technologie” (Förderungsschwerpunkt Mikroperipherik) and “Fonds der Chemischen Industrie” is gratefully acknowledged. We are indebted to Siemens AG (München) for the SAW-devices, Siemens-Elema (Solna, Sweden) for the quartz microbalance and Prof. E. Obermeier, TU Berlin, for the interdigital structures.


Communication: Ring-like structures composed of different numbers of glucose molecules, the cyclodextrins, in which the central cavity (see Figure) can be varied in diameter from 4.7–8.5 Å have been shown to act as specific host materials for a number of halogenated hydrocarbons. The effect, and potential applications as solvent sensors based on quartz-microbalence- and surface-accoustic-wave oscillator devices are discussed.
