Thienylene vinylene dimerization: from solution to self-assembled monolayer on gold.

The electrochemical and spectroelectrochemical studies of thienylene vinylene (TV) derivatives in the immobilized state are compared with the ones obtained in solution. The results highlight the exaltation of the dimerization process onto TV-based self-assembled monolayers, in which the π interaction is maintained even after 75% dilution.
