Organic, supramolecular systems can exhibit extraordinary transport properties [1]. Here we investigate the self-assembly of a carbonyl-bridged triarylamine (CBT) small molecule into helical supramolecular nanostructures [2]. The self-assembly is sensitive to environmental parameters like solvent type and temperature. Using x-ray scattering on the system in various solvents we are able to study the morphology of supramolecular nanostructures formed from CBT molecules. Examining the morphology further with temperature resolved measurements, as well as comparisons of behaviour in solution versus thin films, allows us to learn more about the intermolecular interactions, that are key for their functional properties.
