A sensor detects analytes in a fluid medium by measuring the conductivity of a layer on a carrier with the layer contacting an electrode pair. The layer interacts with the analyte and is improved in that the sensor has a long-term stability and the indication provided by the sensor is completely reversible. The layer is a fullerene layer.

Sensor for detecting analytes in a fluid medium

The invention relates to new polythiophenes containing structural units of the formula ##STR1## in which A denotes an optionally substituted C.sub.1 -C.sub.4 -alkylene radical, their preparation by oxidative polymerization of the corresponding thiophenes and the use of the polythiophenes for imparting antistatic properties on substrates which only conduct electrical current poorly or not at all, in particular on plastic mouldings, and as electrode material for rechargeable batteries.

An electrochemical cell or battery contains two or more electrodes, the active material of one or more of the electrodes consisting of an electrically conductive, electrochemically oxidizable and/or reducible polymer. The electrolyte consists of one or more ionic or ionizable compounds, as conductive salts, dissolved or suspended in an organic electrolyte solvent, the electrolyte containing one or more organic complex ligands possessing ethylene glycol ether units.
