. Dans-un-deuxième-temps, élaboration de structures nanotubulaires, nous avons étudié une série de 1:1[?/?-N ? -Bn-hydrazino]peptides cycliques, et tout particulièrement les cyclotétramères. Dans ce contexte, nous avons cherché à mettre en lumière les différents paramètres pouvant influencer l'organisation nanotubulaires dans nos macrocycles, dans le but d'élaborer la meilleure stratégie afin d'obtenir cette nanostructuration en vues d'éventuelles applications. Les différents paramètres étudiés sont les suivants : la stratégie de synthèse, la chiralité
