Photoswitching Dielectric Properties using Plasmonic Core-Shell Hybrid of 3D C60-Conformers at GHz Frequency
3D-configurated donor-acceptor stereoisomers cis-cup-tris[C60>(DPAF-C9)] were found to exhibit photoswitchable dielectric amplification phenomena using white LED light excitation at GHz frequency. The observation was correlated to the photoactivation of the Au-layer resulting in plasmonic energy to enhance photoinduced intramolecular e−-transfer from DPAF to a C60> moiety. Accumulated plasmonic resonance energy at the near-field surface was effective to distribute negative charges along the outer (C60>)-derived fullerosome shell layer of the trilayered NPs.
