Özet

The electrochemical oligomerization of 2-amino-3-cyano-4-methylthiophene (ACMT) has been studied by cyclic voltammetry, potential controlled electrolysis and digital simulation. The product analysis after preparative electrolysis was carried out by UV-vis-NIR, H-1 and C-13 NMR and FT-IR spectroscopic techniques. The kinetic data were estimated using the results of fitting the digitally simulated voltammograms to the experimentally obtained cyclic voltammograms. The oligomerization proceeds according to an ECE mechanism resulting in the formation of an oligomeric mixture containing dimer and tetramer. UV-vis-NIR and fluorescence measurements indicated that the isolated dimer and tetramer showed higher conjugation than the monomer unit and the conjugation increased with an increase in the number of monomer units.
