Novel 3D-configurated stereoisomers cis-cup-trisC60DPAF-C9 and trans-chair-trisC60DPAF-C9 were designed and synthesized in good yields. The former, with three C60 cages per molecule facing at the same side of the geometrical molecular cup-shape, was proposed to provide excellent binding interaction forces at the gold surface of core-shell -FeOxAuNP nanoparticles and to direct the subsequent formation of a fullerene cage array defined as fullerosome. Upon photoactivation of the Au-layer and cis-cup-trisC60DPAF-C9 itself, the degree of photoinduced intramolecular e-transfer from DPAF to a C60 moiety was found to be largely enhanced by the accumulated plasmonic resonance energy at the near-field surface. Distribution of resulting negative charges along the outer C60-derived fullerosome shell layer of the trilayered NPs was correlated with the detected photoswitchable dielectric amplification phenomena using white LED light at 1.0 GHz.
