NGUYEN, Ha Tran  e  NGUYEN, Le-Thu Thi. Synthesis and characterization of poly(S-2-mercaptoethyl 2-(thiophen-3-yl)ethanethioate) by electrochemical polymerization. Polímeros [online]. 2015, vol.25, n.5, pp.503-507. ISSN 1678-5169.  https://doi.org/10.1590/0104-1428.2208.

A novel monomer of S-2-mercaptoethyl 2-(thiophen-3-yl)ethanethioate (MTE) were synthesized via esterification reaction between 2-(thiophen-3-yl)acetic and ethane-1,2-dithiol in the presence of dicyclohexyl-carbodiimide (DCC) and N,N’-dimethylpyridin-4-amine (4-DMAP) as catalytic system. The structure of monomer was characterized via MS, 1H-NMR and 13C-NMR spectroscopies. The electrochemical polymerization of MTE monomer was performed in acetonitrile using lithium perchlorate (LiClO4) as electrolyte agent. The obtained polymer film (PMTE) was characterized via cyclic voltammetry and it exhibited the main oxidation peaks centered at +2V.

Palavras-chave : polythiophene; electrochemical polymerization; cyclic voltammograms.
