Sintesi di derivati dendritici della trifenilammina per applicazioni opto-elettroniche e catalitiche

In this PhD work we have synthesized and characterized five new linear and four octupolar dyes with II° order non linear optical proprieties. The octupolar dye, containing three pyridyl-triazolyl moieties, has also been used as ligand in the synthesis of mono, bi and trimetallic palladium allylic species. Especially, the monometallic complex shows a better activity in the Suzuki coupling compared to a known complex, bearing a ligand with a single pyridyl-triazolyl moiety. Later, we have developed a synthesis of triphenylamine-based dendritic structures. Particularly, the first generation dendrimer [CHO]3-[G-1]3-[TPA] has reactive superficial groups from which it is possible to extend the structure. Finally, we have prepared fluorescent hybrid materials by adsorption of [Pyr]2-[G-1]-OH on two different TiO2. These solids have been characterized by XPS, TGA-DSC, DRIFT-IR and NMR techniques in collaboration with the University of Malaga.
