摘要： Electrochemical scanning tunneling microscopy (EC-STM) was employed to examine the molecular assembly and electropolymerization processes of 3,4-ethylenedioxythiophene (EDOT) onto reconstructed and unreconstructed Au(100) single crystal electrodes in a 0.1M HClO4 electrolyte solution. The EDOT adsorption onto the Au(100)-hex surface induced lifting of the reconstruction at potentials as low as E=0.150V (vs. reversible hydrogen electrode (RHE)), which is clear evidence of the strong EDOT–Au interaction that was also observed by cyclic voltammetry (CV). EC-STM was also able to reveal, for the first time, the dynamic process of EDOT molecular self-assembly onto the Au(100)-(1×1) surface. The EDOT adlayer was found to fit into a 42×32 unit cell. High-resolution STM imaging revealed a vertically tilted geometry for the EDOT molecules. Electropolymerization was also performed, revealing the solution-process formation of polymer bundles. 出版者： Kidlington: Elsevier Ltd 出版日期： 2012-06-01 出處： Electrochimica acta, 2012-06, Vol.71, p.302-309 版權： 2012 Elsevier Ltd 版權： 2015 INIST-CNRS 識別號： ISSN: 0013-4686 識別號： EISSN: 1873-3859 識別號： DOI: 10.1016/j.electacta.2012.04.010 識別號： CODEN: ELCAAV
