Abstract:
We reported the synthesis of a new series of azobiphenyl based urea derivatives 7 and their stimulus-responsive supramolecular structures in the form of sheet like self-assembled formations. The self-assembled nanostructural formations of azo derivatives 7 are strongly dependent on the nature of the solvent present in the systems. Further, we found that the amide hydrogen played a crucial role in hydrogen bonding interactions to form a sheet like morphology upon stimulus responsive self-assembly. This was confirmed by transmission electron microscopy and atomic force microscopy.

Preparation of 1° Amines: Azide Synthesis
Azide ions act as good nucleophiles and react with unhindered alkyl halides to form alkyl azides. Alkyl azides do not participate in further nucleophilic substitution reactions, thereby eliminating the chances of polyalkylated products. Alkyl azides are reduced by hydride-based reducing agents, like lithium aluminum...
