Recently several stable polymers, for example, polyacetylene (CH) and polyparaphenylene have exhibited large sensitivity to doping. For example, the conductivity of (CH)(x) can be changed by exposure to strong oxidants by nine orders of magnitude. These oxidants, for example, AsF(5), Br(2), I(2) and Cl(2), are toxic, and some of them are widely used in the chemical industry. Most of the change appears at less than 3% of the oxidant present in (CH)(x).
