The synthesis, complete characterization and molecular dynamics simulations of dendrimers 4–8 involving [60]fullerene as core tecton and first‐ to thirdgeneration benzyl‐ether‐based dendrons as branches is described. In dendrimer 7 a core branching multiplicity of 12, the highest known to date, is realized for the first time with a T h ‐symmetrical C 60 core having an octahedral addition pattern. This unique structural type of core building block is only possible on the base of C 60 and has no precedent in organic chemistry. NMR investigations as well as molecular modelling studies show that, owing to high core branching multiplicity, dendrimer 7 and to a minor extent the mixed adduct 8 already represent globular and densely packed macromolecules, although only first‐generation dendrons are involved in their construction.
