- Dependence of single-molecule conductance on molecule junction symmetry
-
The symmetry of a molecule junction has been shown to play a significant role in determining the conductance of the molecule, but the details of how conductance changes with symmetry have heretofore been unknown. Herein, we investigate a naphthalenedithiol single-molecule system in which sulfur atoms from the molecule are anchored to two facing gold electrodes. In the studied system, the highest single-molecule conductance, for a molecule junction of 1,4-symmetry, is 110 times larger than the lowest single-molecule conductance, for a molecule junction of 2,7-symmetry. We demonstrate clearly that the measured dependence of molecule junction symmetry for single-molecule junctions agrees with theoretical predictions.

- SYNTHESIS AND SOME TRANSFORMATIONS OF (2,7-NAPHTHYLENEDITHIO)- AND (2,6-NAPHTHYLENEDITHIO)DIACETIC ACID
-
(2,7-Naphthylenedithio)- and (2,6-naphthylenedithio)diacetic acids were obtained from 2,7- and 2,6-naphthalenedisulfonic acids respectively and were oxidized to (2,7-naphthylenedisulfonyl)diacetic acids with hydrogen peroxide in acetic acid.The nitration of (2,6-naphthylenedithio)diacetic acid leads to the formation of (1,5-dinitro-2,6-naphthylenedithio)diacetic acid.
