Behaviour similar to that of the 'pseudogap' regime in unconventional superconductors is reported in a family of superconducting organic molecular metals. The 'pseudogap' signature that was measured (fluctuating superconductivity above the critical temperature) is most pronounced in those samples that are close to being in a Mott insulating state, suggesting a close relationship between the two phenomena.
