Polyanilines (PANIs) are viable materials for use in optical sensing of pH. Thin films of substituted PANI readily deposit on the inner walls of polystyrene cuvettes when a substituted aniline is chemically polymerized in hydrochloric acid solution. The films have been characterized by absorption spectra which have maxima between 600 and 810 nm, except for halogenated or p-substituted anilines. ...
