Here we report that the morphology of one-dimensional aggregates composed of porphyrins can be controlled by the peripheral hydrogen-bond donating/accepting groups and van der Waals interactions among alkyl chains introduced in the orthogonal axis toward the porphyrin-porphyrin π π stacking axis. The supramolecular assemblies of porphyrin derivatives were monitored by UV-Visible, XRD, SEM, TEM, and HR-TEM. Very interestingly, they afforded a variety of supramolecular morphologies such as helical ribbon, sphere, doughnut, and cylinder depending on the environmental conditions.
