Organic superconductor

In physical chemistry and condensed matter physics, an organic superconductor is an organic compound which exhibits superconductivity at low temperatures. As of 2007 the highest achieved critical temperature for an organic superconductor at standard pressure is 33 Kelvin, observed in the alkali-doped fullerene RbCs2C60.

There are a large number of materials that can be described as organic superconductors. These include the Bechgaard salts and Fabre salts which are both quasi one-dimensional, and quasi two-dimensional materials such as kappa-BEDT-TTF2X, lambda-BETS2X and graphite intercalation compounds and three dimensional materials such as the alkali-doped fullerenes.

All of the above materials are organic, because they all contain carbon. Many of them are also strongly correlated materials, they show phases such as the Mott insulator, antiferromagnetism, a bad metal, charge ordering and, of course, superconductivity.
