Bilayer vesicles as precursors for spherical fractal aggregates from the self-assembly of a C60-fullerene-dyad in polar solvent.
Spherical fractal aggregates of approximately 10 microm were formed from a pi-electronic amphiphile, C(60)-didodecyloxybenzene dyad when extracted from THF into water, necessitating a critical dielectric constant epsilon > or =30 in binary THF-water mixtures. Molecular dynamics simulations revealed the unit cluster to such a form involves an aggregation number approximately 90 with predominant soft associative molecular interactions which corroborated the octadecahedral model proposed for the cluster growth.
