Abstract

ESR, NMR and X-ray measurements were performed for pristine and fully perdeuterio-TMTTF, TMTTF-d₁₂ salts. Significant enhancement by deuteration of the charge-order phase transition temperature, T_CO, was observed in ESR measurements for all (TMTTF)₂X salts measured. No obvious relation between the SbF₆ anion motion and the TMTTF charge-order was found by ¹⁹F NMR. We also performed single crystal X-ray measurements to understand the deuteration effects and temperature dependence of the crystal structure. A possible relationship between the T_CO’s and crystallographical parameters is proposed. The deuteration effects and possible origin of the charge-ordering transition of TMTTF salts are discussed.
