It is shown, for the first time, that single‐component continuous networks of a low molecular weight electron acceptor additive can be grown in a polymer matrix. Such networks can be doped using, e.g., iodine vapor and converted into conductive CT complexes without losing continuity, thereby making the polymer film conductive. Polyethylene films with tetrathiotetracene networks are obtained, and their doping with iodine vapor in air is investigated by means of conductivity and spectrophotometry in the visible range. It is concluded that doping of the surface layer of the microcrystallites is sufficient to observe a significant increase in the film conductivity, which makes possible the use of such systems as sensors.
