Preparation of modified glassy carbon surface with N-(1-H-indole-3yl) methylene thiazole-2-amine and its characterization

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).
