The synthesis of a new type of, and doping mechanism in, “self exchange” or “self-doping” conducting polymers based on 3-(ω-carboxyalkyl)thiophenes (with n = 4-14) is examined (see figure). The properties of the polymers are different to that of those based on the corresponding sulphonic acids due to the lower acidity of the carboxylic acid function.
