Abstract. This work reports on the investigation of sensory properties of thiacalix[4]arene molecules towards volatile halogen-aromatic compounds. Experiments were carried out using the 8-channel sensory system based on Quartz Crystal Microbalance (QCM) technique. Kinetic responses, concentration dependences and detection limit have been obtained. It has been shown that interaction of the sensitive layer with the analyte molecules is substantially defined by the chemical structure of thiacalix[4]arene. Thus, thiacalix[4]arene materials considered in this paper are of great interest for application in the sensory systems of “Electronic Nose” type.

Keywords: QCM sensor, thiacalix[4]arene, halogen-aromatic compounds.
