It is known that the combination of photoswitchable chromophores like azobenzole with different polymers can be achieved in various ways. Our aim is to use the photoinduced change in the chromophore conformation in combination with metal/polymer nanocomposites to develop light switchable resistors, optical filters, Bragg-reflectors, capacitors, or other devices. For the sample preparation we used thermal evaporation from up to three independent sources as well as spin-coating of polymers to produce the different sample morphologies needed. The sample morphology was characterized by TEM microscopy. First results with a focus on the tunable electrical resistances in quasi 2D- and 3D- sample geometries are presented.
