Enabling and understanding new methodologies to fabricate molecular assemblies driven by intermolecular interactions is fundamental in chemistry. We design and study supramolecular coordination polymers at surfaces that behave like supercapacitors, diodes, or exhibit electrochromic and charge-trapping behavior. The position of each molecular component is controlled by the assembly sequences resulting in redox-active films with unique electrochemical and electrooptical properties. Trapped charges can be released by light: exciting nanoscale layers of redox-active metal complexes open-up catalytic pathways for selective electron-transfer. The molecular assemblies are also used for electro- and photocatalysis. We demonstrated electrocatalytic generation of hydrogen and oxygen from water, and their usefulness as light-activated antibacterial coatings.
