    摘要： It is described the use of a tetraphosphonate cavitand of formula (II)

    in which Y = O or S; R = C 4 -C 18 linear or branched alkyl and R 1 = methyl or optionally substituted phenyl, as sensitive material in selective mass sensors for phosphine; also described are new tetraphosphonate cavitands and a method for determining phosphine in caryopses of cereals that foresees the steps of adding sulphuric acid to a sample of caryopses contained in a hermetically sealed container, obtaining an aqueous dispersion; subjecting said aqueous dispersion to microwave heating, taking the gaseous phase overhanging the aqueous dispersion into contact with a quartz crystal microbalance having a mass sensor comprising a quartz disc coated with a layer of a compound of formula (II).
