<dcterms:abstract xml:lang="fr">L'un des plus importants défis mondiaux est le stockage des données, qui est responsable de plus de 2 % de la consommation énergétique annuelle mondiale. Le problème est que la quantité d'informations à stocker augmente chaque année. Notre groupe a trouvé un moyen de stocker l'informations à l'échelle moléculaire. Ces approches tirent parti de la polyvalence de la chimie des polymères. Le problème est désormais de parvenir à stocker de grandes quantités de données. Il est donc crucial d'augmenter la vitesse de synthèse. Dans ce contexte, la chimie radicalaire a été étudiée. Cette chimie hautement réactive pourrait s'avérer prometteuse pour le stockage de données volumineuses. Les monomères sont conçus en trois parties, un radical persistant, un fragment codant et un amorceur radicalaire. Pour initier un radical, deux activations orthogonales sont utilisées. La première est une activation par ATRA et la seconde une photoactivation. La polymérisation peut être contrôlée par des cycles d'activation/couplage.</dcterms:abstract>

The problem is that the amount of information to be stored increases every year. Our group has found a way to store information at the molecular level. These approaches take advantage of the versatility of polymer chemistry. The problem now is how to store large amounts of data. It is therefore crucial to increase the speed of synthesis. In this context, radical chemistry has been studied. This highly reactive chemistry could prove promising for the storage of large amounts of data. The monomers are designed in three parts: a persistent radical, a coding fragment, and a radical initiator. To initiate a radical, two orthogonal activations are used. The first is activation by ATRA and the second is photoactivation. Polymerization can be controlled by activation/coupling cycles.</dcterms:abstract>
