Micrometric band electrodes suitable for the electrochemical investigation of molecular wires were manufactured by lithography. These electrodes are adequate for performing ultrafast voltammetry to ca. 0.5 MV s1 with on-line ohmic drop compensation. At these scan rates, the peak resolution and the reproducibility of the experiment are much higher than when traditional disk or hemispherical electrodes are used due to a better control of the electrode surface state. Hence, this method furnishes a platform for transient studies onto adsorbed molecular electroactive objects.
