Cyclophanes de viologènes adressables pour stockage de charges

Abstract : Storing data on a molecule is a fundamental challenge in developing a system that can store a large amount of data in a minimum of space. The project of this thesis is part of this theme, namely the design of molecular switches oscillating by redox stimuli and being readable without altering the different states to allow the creation of molecular memory. The bis-viologen cyclophanes are therefore potential candidates for the creation of information storage devices that could be reversibly written and read in many ways thanks to the magnetic, optical and conductive properties of the π-dimer. The first chapter of this thesis is devoted to an introduction to the chemistry of cyclophanes and the use of surfaces in the chemistry of cyclophanes and molecular switches. The second chapter deals with the synthesis of viologenes and bis-viologen cyclophanes. The third chapter is devoted to the synthesis of diazapyrenium-viologenes cyclophanes, possible alternatives for bis-viologen cyclophanes.
