Advanced material based on push-pull extended π-conjugated azo-chromophores in functional matrices with enhanced NLO properties

Abstract: Scope of the project SMART-NLO is to obtain, optimize and validate the technology of fabrication and the new product based on novel extended azo chromophores in organo-modified silica films, possesing superior NLO properties at TRL4, developed starting from the preliminary results related to other types of chromophores with nonlinear optical (NLO) properties, filmogenic modified silica films and nanocomposite clay-silica materials obtained at TRL2 already achieved by the team’s publications and the existing laboratory techniques. The method of fabrication of novel material consists in encapsulation of the novel chromophores with extended structures in a silica film rational designed to ensure enhanced nonlinear optical properties. Methods of preparation and composition of the silica filmogenic matrix will be adjust to render tunable and efficient advanced materials with suitable arrangement of chromophore molecules and improved stability, for the fabrication of hybrid materials with superior NLO properties. The methods of film formation are chemicals ones, selected to be energy saving and eco-friendly.
