| 摘要 |
The invention relates to a sensor comprising a piezoelectric crystal with a polyarylene thioethercontaining coating, the coating containing at least one polyarylene system having repeating units of the formula I, -¢(Ar1)n-X!m-¢(Ar2)i-Y!j-¢(Ar3)k-Z!l-¢(Ar4)o-W!p- (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. |
