| Abstract: | Three novel soluble copolymers of pyrrole(P)-thiophene(T)-3-decylthiophene (D) at different molar ratio of comonomers 4 : 1 : 5, 1 : 4 : 5 and 1 : 1 : 2 have been synthesized. NMR, FTIR, UV, emission spectroscopy, GPC, DSC, TGA and conductivity measurements were used to characterize these copolymers. The dark electrical conductivity increases from 3–7 × 10–6 S/m for undoped samples to 10–1–10–2 S/m for samples doped with 4% of iodine, and to 10–102 S/m for 16% of iodine in a form of I3
