The so-called electrostatic layer-by-layer self-assembly method permits to immobilize various functional modules into layered thin film architectures. Adsorption rests primarily on electrostatic interactions of oppositely charged species. Here, we show that immobilization of functional components, such as polyoxometalates (POM), enzymes, or dyes into such multilayers results in layers with interesting properties and devices, including electrochromic windows or sensors. Using this approach it is possible to interface cytochrome <i>c</i> to a surface. The resulting multilayers are electroactive and are interesting model systems to study redox processes and bioelectronic devices. Through the design of the multilayer it is possible to construct materials with polarity gradients capable of vectorial electron transport needed for artificial photosynthesis.
