Molecules with azide functionalities exhibit diverse reactivity and possess considerable "energy richness." One notable characteristic of azides is their remarkable reactivity, attributed to their 1,3-dipolar structure. Consequently, the interest in azides has grown, particularly in their application within the expanding field of click chemistry. Additionally, the photochemistry and thermal decomposition of azides, leading to reactive nitrenes, render them crucial building blocks in material science. This thesis focuses on synthesizing various azide-containing building blocks. Firstly, small aromatic diazides were synthesized and employed in copper-catalyzed azide-alkyne cycloadditions, resulting in the formation of porous structures. Secondly, the synthesis of different potential crosslinkers was investigated. In a third project, C3-symmetric structures based on trimethyl 2,4,6-triaminobenzene-1,3,5-tricarboxylate were prepared, which gave insight into the reactivity of this complex building block.weiterlesen
