Enhanced Charge Localization in the Organic Alloys [(TMTSF)_{;;1-x};;(TMTTF)_x]_2ReO_4
We present a study of the organic alloys [(TMTSF)1−x(TMTTF)x]2ReO4. They exhibit an enhanced charge localization and a strong decrease of the () anion ordering (AO) transition temperature. Contrary to the (TMTDTSF)2ReO4 salt, this behavior does not interpolate that of the x=0 and x=1 pure compounds. It is ascribed to the presence of a 4kF site charge density wave due to the alternate order of the organic molecules, which weakened the 2kF bond response function of the one-dimensional electron gas.
