Thiophene could be a chemical compound with the formula Câ‚„Hâ‚„S. Consisting of a flattened 5-membered ring, it's aromatic as indicated by its intensive substitution reactions. it's a colorless liquid with a benzene-like odor. In most of its reactions, it resembles benzol.
Poly[3,4-(ethylenedioxy)thiophene]
PEDOT is one in every of the foremost the foremost (Fig. 1.51), at first found to be associate insoluble compound, nevertheless it exhibited some terribly attention-grabbing properties like excellent conductivity (≥300 S/cm), electrooptic properties, and processability [44]. due to the changeability between the blue colourise the undoped state and its similar transparency within the doped state (in the visible portion of the spectrum), PEDOT could be a appropriate candidate to be used as a processable conductor in electrochromic displays and will be used in photoelectrochemical cells as associate riveting material. nowadays ICPs supported PEDOT ar commercially offered in multiton quantities. PEDOT is extremely semiconductive in its oxidised (doped) state, wherever the molecular backbone contains mobile carriers.
Thiophene, the only sulfur-containing aromatic compound, with formula C4H4S, that closely resembles benzene in its chemical and physical properties. It happens with benzol in coal tar, from that supply it absolutely was 1st isolated in 1883. Today, thiophene is ready commercially from butane or butylene and sulfur or sulfur oxide. sure thiophene derivatives occur as plant pigments and different natural merchandise. B complex could be a reduced thiophene by-product. The medicine antihistamine (Thenylene) and sure other synthetic pharmaceuticals contain the thiophene nucleus, however there ar few artificial thiophene compounds of importance.
