【 摘 要 】

We designed and synthesized several nanomaterials 3 of three-layered core-shell (γ-FeO_x@AuNP)@[C₆₀(>DPAF-C₉)_1or2]_n nanoparticles (NPs). These NPs having e⁻-polarizable fullerosome structures located at the outer layer were fabricated from highly magnetic core-shell γ-FeO_x@AuNPs. Fullerosomic polarization of 3 was found to be capable of causing a large amplification of material permittivity that is also associated with the photoswitching effect in the frequency range of 0.5‒4.0 GHz. Multilayered synthetic construction allows Förster resonance energy transfer (FRET) of photoinduced accumulative surface plasmon resonance (SPR) energy in the gold layer to the partially bilayered C₆₀(>DPAF-C₉)_1or2-derived fullerosome membrane shell layer in a near-field of direct contact without producing radiation heat, which is commonly associated with SPR.
