The first nucleobase-functionalized polythiophenes, e.g., the uracil-substituted polythiophene shown in the Figure, produced by electrochemical oxidation of bithiophenes covalently linked to the nucleobases uracil and adenine, are reported. Their synthesis, characterization, and polymerization are detailed and the influence of molecular recognition processes on their electronic properties are described.
