Superconductivity emerging from strongly correlated electrons has been expected to have something novel and exotic because interesting phases compete with the superconducting phase in many cases. Superconductivity in quasi-twodimensional ET compounds with the maximum Tc of 14.2 K, which is the highest among the organic superconductors to date, appears in the vicinity of Mott transition. The symmetry of Cooper pair, which reflects the mechanism of superconductivity, is of keen interest. In this chapter, we first review Mott transition in (ET)2X families as a key phenomenon for the emergence of superconductivity. Then, we describe the experimental status of the problem of pairing symmetry by reviewing NMR as well as other measurements probing the superconductive nature.
