“…Since all these phenomena, were new and unexpected the effort was put on a structure made of only one organic stack comprising the lucky TMTSF molecule. Such a structure was already known from the early work of the Montpellier chemistry group who synthesized and studied the series of isostructural X (TMTTF) 2 organic salts [20] where TMTTF is the sulfur analog of TMTTF and X is a monoanion such as 4 ClO , 4 BF or SCN . All these compounds turn into strong insulators at low temperature.…”

“…All these compounds but the one with X= 4 ClO did reveal an insulating ground state with a metal-insulator transition ranging from 180K in X= 4 ReO down to 12K in X= 6 PF , figure 2. In this latter compound the conductivity reached the value of Ω cm at 12K with still a very strong temperature dependence.…”

“…The first practical attempt to promote metal-like conduction between open shell molecular species came out in 1954 with the molecular salt of perylene oxidized with bromine [4] although this salt was not very stable. In the sixties when superconductivity had already turned into practical applications people were worryingnabout the existence of new superconductors which would no longer require the need of liquid helium, W.A.Little made an interesting suggestion [ 5,6].…”

“…X (TM) 2 PERIOD 2.1 Organic superconductivity in X (TMTSF) 2 In 1979, the Copenhagen group succeeded in the synthesis of a new series of conducting salts all based on the TMTSF molecule namely, X (TMTSF) 2 where X is an inorganic anion with various possible symmetry, spherical ( 6 PF , 6 AsF , 6 SbF , 6 TaF ), tetrahedral ( 4 BF , 4 ClO , 4 ReO ) or triangular ( 3 NO ) [36]. All these compounds but the one with X= 4 ClO did reveal an insulating ground state with a metal-insulator transition ranging from 180K in X= 4 ReO down to 12K in X= 6 PF , figure 2.…”

“…The compound (TMTSF) is however the only system in the selenide series in which superconductivity has not been stabilized for reasons related to the peculiar ordering of the anions at low temperature. 4 2 ClO (TMTSF) is the only member of the X (TMTSF) 2 series to show superconductivity under atmospheric pressure [42].…”

The new state of matter (superconductivity) has been discovered somehow unexpectedly in mercury with a critical temperature of T c = 4.15K by Kamerlingh Onnes in 1911 just after he had mastered the liquefaction of helium [1]. However, the phenomenon of superconductivity in particular its T c , is strongly dependent on the material in which it is to be observed. Therefore, over the years a lot of new metals and intermetallic compounds have been discovered with increased values of T c reaching a maximum which was apparently leveling off at about 24 K in the fifties, see figure 1. The absence of any satisfactory theory until 1957 did not prevent the applications of superconductivity which developed after World War Two but all these applications were bound to the use of liquid helium as the cooling agent which is necessary to stabilize the superconducting state. It is only in 1986 that totally new types of copper oxides discovered by Bednorz and Müller led to drastically higher T c [2]. This remarkable discovery was actually an outcome of the quest for new materials able to show superconductivity under conditions as close as possible to ambient temperature. As to the possibility of superconductivity in materials other than metals, F.London in 1937 had been the first to suggest that aromatic compounds under magnetic fields might exhibit a permanent current running along aromatic ring systems (anthracene, naphtalene,...) under magnetic field [3].

The electronic structure and superconductivity of layered organic materials based on the bis(ethylenedithio)tetrathiafulvalene molecule (BEDT-TTF, hereafter ET) with essential intra-ET correlations of electrons are analysed. Taking into account the Fermi surface topology, the superconducting electronic density of states (DOS) is calculated for a realistic model of k k k k k-ET 2 X salts. A d-symmetry of the superconducting order parameter is obtained and a relation is found between its nodes on the Fermi surface and the superconducting phase characteristics. The results are in agreement with the measured non-activated temperature dependences of the superconducting specific heat and NMR relaxation rate of central 13 C atoms in ET. *

In the years since the discovery of conductivity in polyacetylene, a tremendous amount of research has been devoted to the synthesis, characterization, and application development of electrically active polymers. This article reviews the theory of conduction in these materials and discusses the syntheses of the major types of electrically active polymers. Electrical conductivities of these polymers are presented along with stability and mechanical and optical properties. The unique combinations of properties in these materials have led to a wide range of practical applications, which are also discussed.
