  Abstract: A dense monolayer of cobalt(II)   phthalocyanine, CoPc, can be formed on a gold surface by   spontaneous redox deposition followed by vacuum annealing at   about 110 °C. CsCoPc(CN)2 or KCoPc(CN)2 in dilute (∼10-6 M)   ethanol solution rapidly forms a dense adlayer that, when washed   with ethanol, can be imaged by scanning tunneling microscopy,   STM, in air. This adlayer is converted to a monolayer of CoPc by   vacuum annealing as confirmed by STM and X-ray photoelectron   spectroscopy (XPS). This spontaneous surface redox adsorption   process represents a novel method for depositing metallorganic   complexes, which are ultimately only physisorbed on gold.
