从强关联电子中产生的超导性被认为是新奇的，因为在许多情况下，有趣的相与超导相竞争。准二维ET化合物的超导电性出现在Mott转变附近，其最大Tc为14.2K，是迄今为止有机超导体中最高的。库珀对的对称性反映了超导电性的机制，是人们感兴趣的。在这一章中，我们首先回顾了（ET）2X族中的Mott转变作为超导电性出现的关键现象。然后，我们描述的配对对称性问题的实验状态，通过审查核磁共振以及其他测量探测的性质。
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 maximumTc 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.
