Non-stoichiometric potassium fulleride nanowires, KnC60, intercalated into
the pores of mesoporous niobium oxide (see Figure), show conductivity maxim
a that are different from those of bulk fullerides. An interesting result t
hat is attributed to an electronic transition in the material to a cooperat
ive state, in which the structure is no longer acting as a one-dimensional
system, is obtained at n = 4.1.
