We use ZIF-8 nanocrystals modified with cysteamine as buildingblocks in order to assemble films on gold electroactive substrates. Figure5 shows the AFM micrograph of a ZIF-8+Cys film from which we caninfer that the assembly of ZIF-8+Cys produces a stable film that cannotbe removed as modified ZIF-8, compatible with the existence of strongnanocrystal-surface interactions arising from thiol chemisorption over Au.
