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, T GA and conductivity measurements were used to characterize these copolymers . The dark electrical conductivity increases from 3-7 x 10(-6) S/m for undo ped samples to 10(-1)-10(-2) S/m for samples doped with 4% of iodine, and t o 10-10(2) S/m for 16% of iodine in a form of I-3(-).
