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).

Electromechanical systems utilizing suspended conducting nanometer-scale beams are provided and may be used in applications, such as, motors, generators, pumps, fans, compressors, propulsion systems, transmitters, receivers, heat Ingines, heat pumps, magnetic field sensors, kinetic energy storage devices and accelerometers. Such nanometer-scale beams may be provided as, for example, single molecules, single crystal filaments, or nanotubes. When suspended by both ends, these nanometer-scale beams may be caused to rotate about their une of suspension, similar to the motion of a jumprope (or a rotating whip), via electromagnetic or electrostatic forces. This motion may be used, for example, to accelerate molecules of a working substance in a preferred direction, generate electricity from, the motion of a working substance molecules, or generate electromagnetic signals. Means of transmitting and controlling currents through these beams are also described.
摘要:
A method for fabricating tiny field emitter tips (513-516) across the surface of a substrate (502). A substrate (502) is first exposed (504) to reactive molecular, ionic, or free radical species to produce nanoclusters (508) within a thin surface layer (506) of the substrate. The substrate may then be thermally annealed to produce regularly sized and interspaced nanoclusters. Finally, the substrate is etched to produce the field emitter tips (513-516).
摘要:
A functional molecular element having a function controlled by an electric field on a new principle. In the functional molecular element (1), a Lewis base molecule (14) having a positive dielectric constant anisotropy or a dipole moment along the major axis of the molecule is provided in the form of a pendant to a linear or filmy foundation molecule (2) having a conjugated system and exhibiting a conductivity, with a metal ion (3) capable of acting as a Lewis acid interposed between the molecules. When a voltage is applied, the conformation is changed to exhibit the function. The molecules (2, 14) and the metal ion (3) form a complex. When an electric field is applied to the Lewis base molecule (14) in a direction, for example, perpendicular to the paper as shown in Fig. 1(b), the Lewis molecule (14) oscillates within the range of 90 degrees around a vertical axis in the paper plane. When an electric field is applied to the Lewis base molecule (14) in a vertical direction in the paper plane as shown in Fig. 1(c), the Lewis molecule (14) rocks around an axis perpendicular to the paper plane to switch on/off the conductivity of the conducting foundation molecule (2).
摘要:
Disclosed is a functional molecular device displaying its functions under the action of an electrical field. A Louis base molecule (14), exhibiting positive dielectric constant anisotropy or exhibiting dipole moment along the long-axis direction of the Louis base molecule, is arrayed in the form of a pendant on an electrically conductive linear or film-shaped principal-axis molecule (2) of a conjugated system, via a metal ion (3) capable of acting as a Louis acid. The resulting structure is changed in conformation on application of an electrical field to exhibit its function. The electrically conductive linear or film-shaped principal-axis molecule (2) and the Louis base molecule (14) form a complex (6) with the metal ion (3). On application of the electrical field, the Louis base molecule (14) performs a swinging movement or a seesaw movement to switch the electrical conductivity of the principal-axis molecule (2). This molecule exhibits electrical characteristics which may be reversed depending on whether or not the molecule has been subjected to electrical field processing. A molecular device having a function equivalent to one of CMOS may be produced from one and the same material.
