Paper Abstract

Poly(p-xylene tetrahydrothiophenium chloride) was successfully deposited on tapered ends of optical fiber by means of the Layer-by-Layer Electrostatic Self-Assembly method. A posterior thermal curing at low temperatures (around 100°C) is necessary for the synthesis of the conjugated polymer poly (p-phenylene vinylene), (PPV). The fluorescence of this polymer has shown dependence to pH. Optical fiber pH sensors were experimentally demonstrated for the working range from pH 3 to pH 8.
