Charge Transfer Complexes for Organic Metals

The discovery in 1973 of the metal-like electronic behavior of charge transfer complexes, consisting of an electron donor, Tetrathiafulvalene (TTF) and an electron acceptor, 7,7,8,8-Tetracyanoquinodimethane (TCNQ)1)‚ has led to intensive studies of the organic metals.
In 1980 Jérome2), Bechgaad3) and their co-workers have found that each complex of (TMTSF)2PF6 or (TMTSF)2ClO4 using TMTSF analogue of TTF, becomes a superconductor at very low temperatures. Afterwards, organic superconductors utilizing BEDT-TTF4), M(dmit)25) (M=Ni, Pd), etc. have successively been designed one after another. Moreover, the complexes κ-(BEDT-TTF)2Cu[N(CN)2]Br (Tc=11.6K)6), and κ-(BEDT-TTF)2Cu[N(CN)2]Cl (0.3kbar; Tc=12.8K)7) having higher Tc have been found and vigorous studies have been conducted toward the development of still higher Tc organic superconductor.
