Sintesi e caratterizzazione di materiali ibridi fotoattivi

In the last decades material chemistry played a central role in developing new structures both for energy related problems and biomedical application. In particular a number of hybrid organo-inorganic nanostructured systems has been explored for light harvesting and bioimaging. Most of these studies use the inorganic structure as an inert scaffold able to host photoactive molecules. In this work I report my first synthetic efforts in developing novel hybrid structures where the sensitizer is part of the scaffold. In particular I focussed on the synthesis of novel hybrid materials presenting Ce-based nodes and stilbene dicarboxylic acid or p-phenylenediacrylic acid as linkers. Their peculiar properties will be investigated both absorbance and fluorescence spectroscopy, moreover I explore their porosity and thermal stability. Then I developed oligophenilenevinylene and a new squaraine dye in order to use like structral linker for new MOFs never be explored yet. These ligands have shown some better optical proprieties than ligands listed before.
