Functional Polymers: Ionic Polyacetylene with Aromatic Functional Groups
Giseop Kwak,* Sung-Ho Jin, Jong-Wook Park, and Yeong-Soon Gal*
Within the last years, considerable progress has been made in areas like synthesis, characterization, and processing of conjugated polymers. Unfortunately, applications of these promising materials have remained limited because of solubility and thermal instability problems. G. Kwak and coworkers successfully synthesized an ionic conjugated polymer with two aromatic functional groups (pyridyl and phenylene) which proceeded well in polar organic solvents without any additional catalyst or initiator. A conjugated polyacetylene with designed aromatic substituents was achieved; the electrical conductivity of the iodine-doped polymer was 1.20 × 10–3 S cm–1. This polymer showed a photoluminescence maximum peak at 508 nm, and exhibited electrochemical stablility in the rage of –1.32 to +1.92 V.
