A review. Conducting org. polymers, esp., polythiophene and substituted polythiophenes, for use as sensor materials are discussed. The charge transport mechanisms and response toward analytes based on functional groups and charge interactions are outlined. Sensor systems based on triaryl-Me carbocations are described. The design of specific mol. recognition centers to impart selectivity and the nature of the conducting polymer are also discussed. [on SciFinder(R)]
