Résumé | A newly designed module was synthesized and was found to self-assemble into rosette nanotubes (RN) in both water and methanol. Characterization using transmission electron microscopy (TEM) and scanning electron microscopy (SEM) established the formation of analogous RNs in both solvents. However, the chiroptical outcome of the assemblies observed by circular dichrosim (CD) spectroscopy, was found to be mirror image based solely on the solvent used for nanotube formation. As the molecular chirality of the side chains was not changed, yet the supramolecular chirality of the system was opposite in each solvent, a working model was created in which the orientation of the side chains is opposite in each solvent thus causing M and P helical rosette nanotubes. This work represents the first example of solvent-controlled helicity in a self-assembling supramolecular system. |
