dc.description.abstract | This dissertation is mainly concerned with the study of derivatized polybithiophenes preparation using self-assembled monolayer technique and novel electrochemistry. This study proposes four approaches to improve electrical, optical properties and stability of polybithiophenes: 1) BF3??OEt2 used as electrolytic solvent can significantly improve polymer properties by lowering the oxidation potential; 2) Thienylthiolate compound modified electrode can function as a chemical link to allow chemisorption of polymers in a ordered way; 3) Gold nanoparticle modified electrode shows microelectrode feature and polymers obtained display more orientated structure and extended conjugation; 4) Polythiophene / nonaqueous gold nanoparticle complex can be obtained by electropolymerization of monomer and Au nanoparticle mixture. The resulting polymer / metal nanoparticle complex displays exceptional environmental stability in its conductive state. Meanwhile, gold nanoparticles with a series of thienylthiolates monolayer protection are prepared and studied, which demonstrate a solvent-gated electrochemical ensembled Coulomb staircase feature. | |
