Abstract
The objective of this thesis is to understand how the charge transfer takes place at the molecular scale by focusing more particularly on a new family of compounds never synthesized and never studied in the field of organic electronics: dihydro-s-tetrazines.
First, the key parameters that govern the kinetics of intermolecular charge transfer at the scale of one and then several molecules will be studied in order to better frame the study Then, the different ways in which the chemist can intervene to modulate these quantities and in what direction it is interesting to vary them will be discussed in order to get out of the main trends and adapt them to the new family of tetrazine (chapterI). Once these specifications are in place, we will describe the synthesis strategy implemented in order to arrive at these new tetrazines and the methods to functionalize them, in particular using organometallic coupling reactions (chapter II). In the third chapter, we will study the molecular properties of the compounds obtained. First by computational chemistry and then by various spectroscopic and electrochemical measurements.(chapter III). And finally in the last chapter, we will change scale first by considering several molecules then by incorporating them into macroscopic devices for preliminary measurements of charge mobility (chapter IV).
