ABSTRACT:
A sensor material for gases or vapors including solvent vapors, comprising at least one hydrophobic metal complex with an ion mobility or ionic concentration or optical properties, which change under the effect of the gas or vapor. These metal complexes can be applied to suitable electrode arrangements or carriers and, in conjunction with simple measuring bridges or photometers, form a sensor system for gases and vapors.
