- Abstract
- We report on the study of a molecular torsional
switch made up of two distinct aromatic moieties bound by
an acetynil group. The mechanism of operation is based on
the action of a static electric field perpendicular to the ring
ring bond which modifies the torsional angle and, as a consequence,
the inter-ring conjugation. The current is computed
with a method based on the molecular Greens function, in
which the electrodes are taken into account in an effective
way. The current/voltage profile at several dihedral angles
shows that the current is maximum for the planar conformation
and decreases by a factor <1000 for the orthogonal
conformation, suggesting the potential applicability of
the proposed switching function in devices at the molecular
scale. (literal)
