| A novel polymers that have triphenylamine derivative including ether bonds in the main chain were synthesized by chemical oxidative polymerization using FeCl3 as an oxidant. The reaction conditions were optimized to yield linear polymers with high molecular weight. The best conditions were 4 times to monomer and at 40°C. The polymers had good solubility in organic solvents such as chloroform and toluene. Polymers provide thin films with good quality by casting or spin-coating from polymer solutions. Cyclic voltammometry showed that they had a reversible electrochemical activity. Hole mobility of polymers that have ether bonds was 5.18 ~ 4.42 × 10^-5 (cm2/V∙s) at 45V/ μm, which is higher than PBTPA. This indicates that ether oxygen promote the hole mobility due to the electron donation leading to the stabilization of the cation radical, or hole. |
