The dendronization is a synthetic methodology that offers important advantages. The products formed, named dendronized materials, present new and specific properties. This report shows examples in which individual dendrons and hyperbranched molecules are used as building blocks to prepare more complex arrays vianon covalent interactions. In particular, it points out how in the dendronization process the structural information programmed into the dendritic architecture can be used to generate nanostructures with specific tailored properties. Cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) and atomic force microscopy (AFM) were used to monitor the self-assembly processes of dendritic molecules onto carbon surfaces. The electroanaytical exploitation of these dendronized surfaces was also investigated. Expuso: FARÍAS, E.D.
