dc.description.abstractOstwald ripening allows the synthesis of 1D nanorods of metal and semiconductor nanoparticles.However, this phenomenon is unsuccessful with organic π-systems due to their spontaneous self-assembly to elongated fibers or tapes. Here we demonstrate the uses of light as a versatile tool to control the ripening of amorphous organic nanodots (ca. 15 nm) of an azobenzene-derived molecular assembly to micrometersized supramolecular rods. A surface-confined dipole variation associated with a low-yield (13−14%) trans−cis isomerization of the azobenzene moiety and the consequent dipole−dipole interaction in a nonpolar solvent is believed to be the driving force for the ripening of the nanodots to rodsen_US
