Cover Story: The TMTSF cation constituted the first organic superconductor, reported in 1980. It is interesting to investigate the effect of 4f electrons on the conductivity properties of TMTSF cations. The 4f electrons have large anisotropic magnetic moments due to strong spin-orbital coupling. The use of the polyvalent 4f metal complex as a counter-anion also indicates a different degree of conduction band filling in the radical of TMTSF molecules, compared to that of monovalent anions such as PF6, Cl, I. In this work, a new molecular conductor of (TMTSF)5[Dy(NCS)4(NO3)2]CHCl3 was prepared by the electrochemical oxidation method. The crystal shows anisotropic one-dimensional semiconducting behavior with a room temperature conductivity of 0.2 S·cm−1 and an activation energy of 34 meV at ambient pressure. View this paper
