This work of thesis has been done at the University of Insubria of Como under the
supervision of the Ph.D. coordinator Professor Norberto Masciocchi.

I thank respectfully Professors Paolo Quadrelli, Umberto Piarulli, Louis Fensterbank and Dr Kevin
Cariou for doing me the honor of judging my work of thesis stealing time from their commitments.

At the end of these studies, I want to express a sincere acknowledge to my tutor since a long time
Professor Gianluigi Broggini, friendly called Gianni, from whom I aquired all my knowledges. He
helped and incited me during these years with perseverance. Thank you for your friendliness,
patience and comprehension.

I thank immensely Professor Giovanni Poli, my other tutor, which hosted me in his laboratories for
one year in Paris (University Pierre et Marie Curie). I felt as at home after only a few days. Thank you
for your willingness and for you support.

Morever, my special thanks goes to Dr Julie Oble, without her, it would have been so difficult to
become familiar with the new lab and the new labmates. She has been friendly since the beginning,
she pushed me to be more confident and I felt supported by her in every situation.
At the end of this “adventure”, I go out grown due to this three people. I am grateful for what you
have done for me.

Of course, I thank the entire lab group, both the Italian and the French one for the good atmosphere
in the lab, during our lunches and the coffee breaks. I should mention too many people, to all of you
thank for been there with me when I felt alone or sad or just for laughing together.

Especially, thank you Silvia to be one of my best friends, to be always there for a chemical advice of
for a crazy techno night together  I really felt your lack this year…

In the end, the bigger thanks goes to my friends of a life, Mary, Frenci, Ila, Ste and Marti for
encouraging me every day. Last but not least, the two most important people in my life, Fabio and
Anna.

Yours, Daria
