Abstract

Atomic force microscopic studies have been conducted for insight into the morphological aspects of monochelic porphyrin and fullerene complexes forming fibrils of continuous nature. Alternating dark and bright segments could be envisioned clearly, as individual porphyrin-fullerene repeating units. These fibrils also caused a remarkable red shift in the soret band absorption of porphyrin. Dynamic light scattering analysis was also conducted under different solvent conditions, which showed the swelling of fibrils when the solvent was changed from THF to water.
