title: New colorimetric and fluorometric chemosensor based on a cationic polythiophene derivative for iodide-specific detection.
abstract: Electrostatic interactions between anions and a new water-soluble, cationic, affinitychromic poly(3-alkoxy-4-methylthiophene) derivative provide a new tool for a selective optical detection method (colorimetric or fluorometric) for iodide ions.
