K 3 C 60 has been quantum‐confined inside the pores of mesoporous niobium oxide . Examination of the electronic properties of this new family of 1D potassium (shown in pink in the Figure) fullerides shows that, contrary to previous experimental data on bulk K 3 C 60 (but consistent with theoretical calculations), these nanowires are insulating at room temperature and do not undergo a superconducting transition at liquid‐helium temperature.
