Analyte-induced aggregation of conjugated polyelectrolytes: role of the charged moieties and its sensing application.
The vital role of the charged moieties of monovalent aromatic anions in regulating the aggregation of a cationic conjugated polyelectrolyte was exploited in terms of the hard-soft acid-base principle and its application to colorimetric sensing of taurine was examined.
