Abstract
Polyaniline (PANI) with electron-donating and electron-withdrawing substituents were electrodeposited and studied as sensing materials in conductometric transducers. Whereas the dimethoxyaniline leads to a highly conductive material, the tetrafluoroaniline leads to a poor conductive polymer. However, it was used in heterojunctions. Elsewhere, hybrid materials combining polypyrrole (PPy) with ionic macrocycles as counterions were also electrosynthesized and used as sensing material for the detection of ammonia. They exhibit a higher sensitivity compared to PPy prepared with small counterions, with a stable response in a broad range of relative humidity and at room temperature.
