摘要: The piezoelectric thickness-shear-mode (TSM) acoustic wave sensing device was fabricated by coating with a calixarene derivative on the surface of gold electrode quartz crystal, then connecting transistor-transistor-logic (TTL) oscillator, frequency counter and computer. Among four materials, compound I most efficient active material for adsorption carbinol molecule based host-guest recognition mechanism. In comparison gas chromatography (GC) method, TSM can be used on-line determination poisonous vapor in range 0 ~ 3000 ppm around our living environment good selectivity, reproducibility high stability. detection limit evaluated to 1.41 ppm.
