Triarylamine-based supramolecular polymers: structures, dynamics, and functions

Supramolecular electronics rests on the self-assembly of organic nanostructures that display optimized charge transport properties and that can be readily integrated in miniaturized devices by a bottom-up approach. By controlling light-responsive triarylamine molecules we have demonstrated the possibility to pre-determine the self-construction of organic interconnects within micro- and nano-circuitries. Along this main line, we will describe the detailed mechanisms of the supramolecular polymerization which involves complex nucleation/growth processes. We will show that supramolecular polymerization can be extended to a number of advanced triarylamine derivatives for the production of various hierarchical structures in solution and in confined spaces. We will also discuss the optical, magnetic, and electronic properties of these supramolecular polymers which reveal metallic signatures. We will finally highlight how the presence of such metallic electrons in these organic materials can be used for the formation of supramolecular plasmonic waveguides and interconnects.
