Photoswitching Dielectric Properties using Plasmonic Core-Shell Hybrid of 3D C60-Conformers at GHz Frequency

3D-configurated donor-acceptor stereoisomers cis-cup-tris[C
₆₀
>(DPAF-C

)] 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
