摘要:
A functional molecular element whose functions can be controlled by an electric field based on a new principle. A Lewis base molecule (14) with positive permittivity anisotropy or a dipole moment in the major axis direction of the molecule is disposed, via a metal ion (3) that can act as a Lewis acid, in a pendant-like form on a key molecule (2) in the form of a line or film that has a conjugated system and exhibits conductivity, thereby forming a functional molecular element 1 that can realize a function where the conformation changes due to the application of an electric field. The conductive key molecule (2) and the Lewis base molecule (14) form a complex with the metal ion (3). When an electric field is applied in a direction perpendicular to the plane of the paper in FIG. 1(b), for example, the Lewis base molecule (14) performs a 90° “neck twisting” movement with the up-down direction in the drawing as the axis. Also, when an electric field is applied in the up-down direction in the drawing as shown in FIG. 1(c), the Lewis base molecule (14) performs a “see-saw” movement with the direction perpendicular to the plane of the paper as the axis, thereby switching the conductivity of the conductive key molecule (2).
摘要:
A functional molecular element exhibiting its function under the operation of an electrical field is provided. A compound is used in which a pendant molecule, formed by 4-pentyl-4′-cyanobiphenyl, exhibiting positive dielectric constant anisotropy or a dipole moment along the direction of the long axis of the molecule, is covalently bonded to an electrically conductive linear or film-shaped principal-axis molecule having a conjugated system. The pendant molecule is changed in its orientation on application of an electrical field to change the conformation to switch the electrical conductivity of the electrically conductive principal-axis molecule.

摘要:
Between each transparent pixel electrode driven by TFT as a drive device and a common electrode, a polymer layer located in contact with the transparent pixel electrode and electrically active to change in color by electrochemical oxidization or reduction and a polymeric solid electrolytic layer located in contact with the polymer layer and containing a coloring agent are interposed. Since electrochemical oxidization or reduction brings about a color change, the contrast and the black concentration can be enhanced, and bronzing after long-time use does not occur.
