1. An ionic superatomic material comprising a metal-containing superatom and a fullerene derivative,
wherein the metal-containing superatom is selected from the group consisting of Co6Te8(PR1R2R3)6, Co6Se8(PR1R2R3)6, Ni9Te6(PR1R2R3)8, Cr6Se8(PR1R2R3)6, Cr6Te8(PR1R2R3)6, Re6Se8(PR1R2R3)6, Re6Te8(PR1R2R3)6, Au25(SR)18, Au38(SR)24, and derivatives thereof, and
wherein the fullerene derivative is selected from the group consisting of C20, C70, C72, C74, C76, C78, C80, C82, C84, C86, C88, C90, [6,6]-phenyl-C61-butyric acid methyl ester (PCBM), C60-COOH, C70-COOH, pyrazolino[60]fullerene, methano[60]fullerene, isoxazolino[60]fullerene, [60]ThCBM, [60]PCB-C8, [60]PCB-C4, and [70]PCBM,
wherein R1, R2, and R3 are independently straight or branched chain C3-C20 alkyl groups.
