Özet

N-(1-H-indole-3yl) methylene thiazole-2-amine (IMT2A) was oxidized at a glassy carbon (GC) electrode surface in acetonitrile containing 0.1 M tetrabutylammonium tetrafluoroborate (TBATFB) to prepare a modified electrode. Surface modification experiments were performed using cyclic voltammetry with the potential range of 0.8 to 1.6 V with a scan rate of 100 mV s(-1) for 15 cycles in 1 mM IMT2A solution. The modified GC surface (IMT2A-GC) was characterized by cyclic voltammetry, electrochemical impedance spectroscopy, contact angle measurement, profilometry, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy and atomic force microscopy. The number of electron transferred and diffusion coefficient of IMT2A were calculated by using an ultramicroelectrode (UME). (C) 2013 Elsevier B.V. All rights reserved.
