Abstract

Poly(3-hexylthiophene) (P3HT) is an important basic material that is widely used in p-type semiconductor devices for organic solar cells and transistors. time. However, the change is dramatically suppressed in comparison with the initial reaction. This supports that there is polymer adsorption on the ferric chloride particles that regulates formation of the radical cation on the 3HT. In short, the adsorbed polymer appears to poison the catalytic behavior. To clarify the effect of solvent on the polymerization, researchers replaced chloroform with hexane and carried out the reaction under similar conditions. The polymerization is initiated when two radical cations react. A pair of protons departs at the extended part of the dimer to form a neutral structure. Another radical cation is then generated at the end of the extended polymer chain due to reduction of Fe(II), propagating the reaction. Through this reaction, a polymer with high molecular weight is formed.
