Functional materials are nowadays used in many applications, e.g. in nanotechnology, catalysis, chemical sensing, gas separation, energy transformation and storage as well as in electronics. For materials improvement by rational design the knowledge of structure-function-relationships are essential [1]. Thus we synthesize inorganic/organic hybrid materials from versatile building blocks and extensively characterize them with modern analytical methods of surface and solid state science. Especially, the interactions of the materials with nearby molecules are in our centre of interest to apply them as chemisensitive materials. Therefore finally, we investigate the properties and sensing function of the materials "in -situ" to correlate all results and gain insight in the structure-function-relationships of the material. This allows us to strategically develop materials with better performances. In the talk, results of metal-organic frameworks [2] as well as of metal nanoparticle composites will be presented [3].
