Disentangling the chemistry and physics behind reported unconventional superconductivity and exotic magnetism in alkali-intercalated PAHs has remained problematic due to the lack of phase-pure samples. Two synthetic pathways have now remedied this issue, facilitating studies of cooperative electronic properties based on carbon π-electrons.
