    摘要: Hyperhalogens, a new class of highly electronegative species, are now invented. A hyperhalogen is a superhalogen-containing composition in which the electron affinity (EA) of the hyperhalogen is even larger than that of the superhalogens they are composed of. Novel production methods are provided in which highly electronegative species are produced by surrounding a central metal atom by superhalogen moieties.
