The design and assembly of functional soft materials in the form of stimuli-responsive organic mono- and multilayers offers a great challenge that promises new device properties, enhanced performance, and eventually, affordable production costs. We recently demonstrated that charge storage in well-defined metal complexes covalently attached to silicon-based surfaces results in a reversible change in the optical properties of the system. The chemical sensitivity and the stability of these films over a number of redox cycles make these systems suitable candidates for a new generation of non-volatile memory elements, sensors, and Boolean Logic gates.
