“…Among these polymers, polypyrrole (PPy) [1], polythiophene (PTh) [2,3], polyfuran (PFu) [4][5][6][7] and their derivatives [8][9][10] have been thoroughly investigated. The properties of these polymers can be modified significantly by the substitution of H-atom at the 3-position of the thiophene or pyrrole rings with a long alkyl chain.…”
