Based on our results achieved in the 1st project phase, we aim to synthesise and characterise novel nanomaterials by means of covalent bonding of (oligo)phenothiazines in the pores of ordered mesoporous materials (e.g. MCM-41). After having determined the optimum linker function by conducting extensive investigations, the research focus in the 2nd project phase will be: -the bonding of oligophenothiazines able to adopt several stable redox states  -the implementation of functionalities for the pre-organisation of electrochromophores in solution during material synthesis We expect a far better interaction between the dyes than through a static incorporation into the hybrid materials. Such systems possess potential application as new electrochromic and photochromic nanomaterials and as electrode coatings in sensor technology.
