WebDec 24, 2008 · Polythiophene-based polymers are an important class of organic semiconductors that serve as the building blocks for polymer-based hybrid solar cells. These polymers are susceptible to oxidative photodegradation in air. A model water-soluble polymer, the sodium salt of poly[2-(3-thienyl)ethoxy-4-butylsulfonate], was employed to … WebNote that below ∼20 K the scatter of S for polythiophene obviously different from σ is an order of magnitude larger than poly(3-methylthiophene), indicating the lower conductive regions in polythiophene. 14 This implies that the methyl side group can lead to a different transport property in the crystallized regions likely due to a higher crystallinity in poly(3 … The optical properties of these materials respond to environmental stimuli, with dramatic color shifts in response to changes in solvent, temperature, ... Many different oxidants are used. Because of the redox reaction, the conductive form of polythiophene is a salt. An idealized stoichiometry is shown using … See more 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.
