C. Yoshikawa, Ying Bao, Herman J. Geise] We report the synthesis of a novel poly(p-phenylene-vinylene) derivative bearing dodecanoylsulfanyl side-groups (12COS-PPV). Good solubility in organic solvents was achieved. The average molecular weight was around 30 000, the energy gap 2.8 eV and the thermal stability up to 130°C. Doping with iodine vapours rose conductivity to 2·10-6 S/cm. Gas sensors made from FeCl3-doped 12COS-PPV showed an unusual behaviour responding to only four of the eight different organic solvent vapours tested. Recoveries from the responses are not complete, but are reproducible and can be used to discriminate between the four solvents. Quantitative analyses are also possible since there is a good linear correlation between relative response and concentration. © 2013 by Walter de Gruyter GmbH & Co.
