Polythiophene polymer
WebRegioregular polythiophenes have been widely used in organic electronic applications due to their solution processability with chemical modification through side chain engineering, as … Polythiophenes (PTs) are polymerized thiophenes, a sulfur heterocycle. The parent PT is an insoluble colored solid with the formula (C4H2S)n. The rings are linked through the 2- and 5-positions. Poly(alkylthiophene)s have alkyl substituents at the 3- or 4-position(s). They are also colored solids, but tend to be … See more PT is an ordinary organic polymer, being a red solid that is poorly soluble in most solvents. Upon treatment with oxidizing agents (electron-acceptors) however, the material takes on a dark color and becomes electrically … See more Polythiophene and its oxidized derivatives have poor processing properties.
