High-resolution topographic information has been be achieved with an electrochemical atomic force microscope on a weakly adsorbed porphin adlayer. The substrate was an iodine-passivated Au(111) facet, and an electrolyte containing perchloric acid was used. The already well-known lateral structures were reproduced. New information about the height of different parts of the porphin complex and its adsorption forces is presented.
