As a final example, let us mention that Little 143,144) has discussed the possibility of obtaining organic superconductors that operate at high temperature. The first superconductive model compound to be proposed was a polymethine chain connected with highly polarizable sensitizing cyanine dyes (see e.g. Table 3). The first report on superconducting fluctuations in tetrathiafulvalene-tetra-cyanochinodimethane crystals appeared recently 145>. 2... 

Future developments in this field will surely be dominated by issues relating to the limited dimensionality of the compounds so often found in the organics. As alluded to earlier, such concepts as limited dimensionality and quasi-one-dimensionality were not part of the everyday vocabulary of condensed-matter physics, nor were they part of the world of superconductivity until work focused on problems of organic superconductors. It was this that brought these concepts to the fore, notably through work in the late 1960s of Ferrell [37], Rice [38], and Hohenberg [39] on fluctuations and the innovative microscopic treatment of competition between super-... 

As I have said in the past, it seems to me that the best candidates [for 300-400 K] are organic superconductors and inorganic layered compounds, particularly intercalated ones. ... 

A thermodynamic quantity not very often measured for organic superconductors is the specific heat, C. Usually the crystal sizes are rather small and consequently a high sensitivity of the apparatus is needed. In most experiments, therefore, an assembly of many pieces of material is necessary to gain better resolution. In addition, the jump of C at Tc is expected to be rather small especially for compounds with higher transition temperatures because of the comparatively large lattice contribution to C owing to the low electron density and the low vibrational frequencies. 

This is drastically different for heavy Fermion compounds where extreme enhancement factors are known. Therefore, the organic superconductors were compared and related to this latter unique class of metals [284].
