Structure and Phase Diagram of Organic Superconductors

Abstract

The organic superconductors or molecule-based superconductors have been realized with charge transfer complexes in which donor and acceptor molecules are paired. In most organic superconductors, the electronically dominant molecule has TTF-type skeleton acting as donor as illustrated in Fig. 1. M(dmit)₂ type molecule is exceptional and acts as acceptor. Tables 1 and 2 lists the organic superconductors consisting of donor molecules of TTF-derivative. The salts with symmetrical molecules are given in Table 1 while the salts with nonsymmetrical TTF-derivatives are listed in Table 2. The molecule-based superconductors with M(dmit)₂ are given in Table 3. The fullerene salts are listed in Table 4.
