The results of the study of the optical properties of conducting polymers - derivatives of PEPC with heavy atoms are presented. It is shown that a heavy atom in a polymeric molecular structure leads to hypsochromic shift of the absorption spectrum. Fluorescence spectra practically do not change their position. In the spectra of PEPC with heavy atoms there are several bands. The long-wavelength emission band with a maximum around 420 nm belongs to the emission of “sandwich” type excimers. Short-wave band at 380 nm is related to the eclipse type excimers. In the polymer films of PEPC excimers of first type are more effectively formed. Heavy atom changes the ratio of the excimer fluorescence bands.
