Supramolecular self-assemblies of triarylamines : fundamental studies and applications

Abstract : In this thesis, we have explored the fundamental mechanism of the thermally initiated self-assembly process of chiral triarylamine trisamides. The results demonstrate a cooperative nucleation and growth mechanism with well-defined thermal hysteresis and memory effect. We have then studied the possible implementations of triarylamine derivatives in various fields of material sciences. First, by taking advantage of a biocatalytic approach, we managed to control the self-assembly of TAA-peptide amphiphiles in water. Second, new triarylamine derivatives were successfully inserted as hole transporting layers in perovskite solar cells. Third, the self-assembly of triarylamines was triggered electrochemically, leading to an anisotropic construction of conducting nanowires. Finally, we developed a technique that allows for the highly ordered alignment of gold nanoparticles over a layer of triarylamine nanowires at the liquid-liquid interface by simple centrifugation of a biphasic mixture.
