Abstract

General patterns: A photoisomerizable nitrospiropyran monolayer associated with a gold surface enables the photolithographic patterning of the surface with nitromerocyanine domains. The selective association of Co2+ ions on the nitromerocyanine domains (red) allows the electrochemical generation of magnetic Co0 nanoparticles (NPs) on these domains. The magnetic information can be electrochemically erased and restored. (Figure Presented).
