P. Audebert et al., ELECTROCHEMICAL DEMONSTRATION OF THE EXIS TENCE OF P-DIMERS OF CATION-RADICALS OF THIOPHENE OLIGOMERS IN SOLUTION, Journal de chimie physique et de physico-chimie biologique, 92(4), 1995, pp. 827-830
alpha-alpha'-disubstituted oligothiophenes of various lengths have bee
n studied by cyclic voltammetry in a (30/70) acetonitrile/toluene mixt
ure and in pure acetonitrile. The pi-dimer existence domain have been
determined by the variation of the redox potentials with the temperatu
re and the initial concentration.
