Did you know?
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. They are insoluble in ordinary solvents and do not melt readily. For example, doped unsubstituted PTs are only soluble only exotic solvents such as arsenic trifluoride and See more Electrochemical synthesis In an electrochemical polymerization, a solution containing thiophene and an electrolyte produces a conductive PT film on the See more • Handbook of Conducting Polymers (Eds: T.
