Özet

In this work, electrochemical behaviors of 2,5,8-trioxa-16,20- diazatricyclo[20.4.0.09,14]-hexacosa-9,11,13,15,20,22,24,26-octaene (TPO) was investigated and mechanistic study was achieved in 0.1 M tetrabutylammonium tetrafluoroborate (TBATFB) in acetonitrile on glassy carbon (GC) working electrode by cyclic voltammetry, chronoamperometry and chronocoulometry. It was estimated by ultra microelectrode (UME) that this molecule is reduced by four-electron transfer. The reduction product adsorbed on the electrode surface, characterized by Raman spectroscopy, is a dimer. It was determined by using cyclic voltammetry that TPO is electroreduced by EC mechanism. Using digital simulation studies, EC mechanism was also indicated and the standard rate constant of the reduction step was calculated as well as the rate constants of the homogenous reaction. © 2005 Wiley-VCH Verlag GmbH & Co.
