Abstract
The invention relates to a sensor comprising a piezoelectric crystal with a polyarylene thioether-containing coating, the coating containing at least one polyarylene system having repeating units of the formula I,
which contain at least one thioether group, in which
Ar1, Ar2, Ar3 and Ar4 are identical or different aryl systems having from 6 to 18 carbon atoms,
W, X, Y and Z are identical or different linking groups, selected from the group comprising —SO2—, —S—, —SO—, —O—, —CO—, —CO2—, alkylene or alkylidene having from 1 to 6 carbon atoms and —NR1—, where R1 is an alkyl or alkylide group having from 1 to 6 carbon atoms and at least one linking group must be —S—, n, m, i, j, k, l, o, p are, equal or different, integers zero, 1, 2, 3 or 4, their sum having to be at least 2, and to the use thereof.
