Electrosynthesis and Characterisation of Alkylester-substituted Polythiophenes

Thiophenes containing alkylester groups in the beta position of the ring have been electropolymerized on Pt. The fraction of the polymer films that became soluble in chloroform has been analysed by spectroscopic techniques and by size exclusion chromatography, with the aim of comparing them with the chemically prepared corresponding macromolecules. The electrochemical behaviour, i.e., the charge process of the polythiophene coatings, has been studied and the relevant parameters have been discussed.
