Electron switch in the double-cage fluorinated fullerene anions, e(-)@C20F18(XH)2C20F18 (X = N, B): new candidates for molecular quantum-dot cellular automata.

A new type of molecular quantum-dot cellular automata (MQCA) candidates is suggested using the double-cage fluorinated fullerene molecules, e(-)@C(20)F(18)(XH)(2)C(20)F(18) (X = N, B), which have bistable charge configurations that could be used to encode binary information. The electron switch between the two cages leads to the QCA function.
