Bithiophenes, when used as starting material for polythiophene synthesis, offer advantages over corresponding thiophenes. Polymerization proceeds at lower oxidation potentials and lower monomer concentration and gives polymers with higher yield and b

FeCl− doped polythiophene, iodine doped Shirakawa polyacetylene and an ultrathin film of undoped poly(4,4'-dibutyl-2,2'-bithiophene) have been studied by scanning tunneling microscopy (STM). The polythiophene shows a lamella-like structure with a t

Chemical polymerization of 4,4′-dialkyl-2,2′-bithiophenes is reported. The resulting soluble polymers can be cast from their chloroform solutions to give thin layers and free-standing films, which can be doped by electrochemical and chemical meth

The influence of additives on the electrochemical oxidation of polyacetylene in acetonitrile and dichloromethane has been evaluated. Of the ten tested substances only bithiophene showed a significant positive effect. It is believed that this is due t

Pyrrole can be electrochemically polymerised onto polyacetylene anodes. The morphology of the resulting conducting composites depends on the initial doping state (e.g. conductivity) of the polyacetylene. The air and water stability of the conducting

The result of the electrochemical oxidation of polyacetylene is improved by additives in the electrolyte, which suppress overoxidation of polyacetylene. The temperature dependence of the conductivity is semiconductor-like and is interpreted by Sheng'
