The goal of the Institute was to demonstrate the breadth of chemical and physical knowledge that has been acquired in the last 20 years in inorganic and organic crystals, polymers, and thin films, which exhibit phenomena of reduce

Frontiers of Organic Superconductorsmber of organic systems is still less than 1%, and the maximum T. is less than 1/10 of those of inorganic systems (Fig. 1). It is an urgent task for chemists to explore a variety of new organic superconductors, and to extend T. to the range of 15 – 20 K, at least.

Nevertheless, this superconducting state at 8 K in β.-(BEDT-TTF).I. is only metastable [6,7], since warming up the crystal above 125 K, and cooling down again under ambient pressure, results only in superconductivity at 1.3 K, the so-called β. - or β-phase.

Electron Paramagnetic Resonance of Organic Conductors (BEDT-TTF)2X two insulating phases β′ and α′ show Bonner-Fisher type one-dimensional antiferromagnetic behavior, with transitions to a spin-density wave and a spin-Peierls ground state, respectively. These observations are finally correlated with conductivity and reflectivity measurements, and are discussed in terms of the calculated band structures.

Structural Properties of Molecular Charge-Transfer Conductors and Semiconductors from Infrared and Rods are widely used to evaluate electronic band structure parameters.. Organic charge transfer (.) crystals, as molecular conductors and semiconductors, share some properties of both the above classes of solids, and, therefore, new spectroscopic phenomena are expected, and indeed observed for these materials..
