Recent progress on conducting organic charge-transfer salts

One of the clear manifestations of electron correlation in condensed matter is metal–insulator (MI) transition. The organic conductors κ-(ET) 2 X and (DCNQI) 2 M are contrasting textbook materials ...

Metal–Insulator Transition in κ-(ET)2X and (DCNQI)2M: Two Contrasting Manifestation of Electron Correlation

DCNQIs—new electron acceptors for charge‐transfer complexes and highly conducting radical anion salts

Present status of experiments on charge ordering (CO) phenomena observed in organic molecular conductors is reviewed. Experimental techniques to detect and analyze the CO, i.e., NMR, X-ray and Infrared/Raman spectroscopy, are described and the experimental results in typical materials exhibiting CO are summarized. (DI-DCNQI) 2 Ag, (TMTTF) 2 X, α-(BEDT-TTF) 2 I 3 , θ-(BEDT-TTF) 2 RbZn(SCN) 4 and related materials are discussed. Charge disproportionation without long-range order observed in numbers of materials are also included.
