Chirality inversion in hydrogen-bonded rhodanine-oligothiophene derivatives by solvent and temperature

The self-assembly process of hydrogen-bonded quinquethiophene - rhodanine derivatives has been explored as a function of solvent and temperature. We demonstrate the divergent supramolecular chirality emerging from a single enantiomer by subtle changes in solvent mixtures and sample preparation proto...

Description
Summary:The self-assembly process of hydrogen-bonded quinquethiophene - rhodanine derivatives has been explored as a function of solvent and temperature. We demonstrate the divergent supramolecular chirality emerging from a single enantiomer by subtle changes in solvent mixtures and sample preparation protocol. Spectroscopic techniques have proved the presence of aggregates where H-bonding interactions play a crucial role. Inversion of supramolecular chirality with a single enantiomer of a hydrogen-bonded pi-conjugated system is achieved by applying external stimuli such as solvent and temperature.
