    • A functional molecular element with a reduced contact resistance between the constituting molecule and the electrode, a method for production thereof, and a functional molecular device are provided herein. The method consists of the following steps. A closely adhering molecular monolayer is formed on the surface of the electrodes from a π-electron conjugated molecule (one species of linear tetrapyrrole) composed of the porphyrin-like nearly discoid skeleton and the flexible side chains (alkyl chains). A π-electron conjugated molecule of the same species as the one or different species from the one is piled on the monolayer by π-π stacking to form the array structure. As the result of the foregoing steps, the π-electron conjugated molecule constituting the first molecular layer of the array structure takes on such a configuration that the flexible side chains adsorb to the surface of the electrode and the discoid skeleton orients parallel to and adheres to the surface of the electrode. The second and subsequent molecular layers constituting the array structure have their piling direction controlled by the π-π mutual action.
    • 本文提供了构成分子与电极之间的接触电阻降低的功能性分子元件,其制造方法和功能性分子器件。 该方法由以下步骤组成。 由卟啉样的近似圆盘状骨架和柔性侧链(烷基链)构成的π电子共轭分子(一种线性四吡咯)形成电极表面上紧密分散的单层。 通过pi-pi堆叠将与一种或不同种类相同物种的π电子共轭分子堆叠在单层上以形成阵列结构。 作为上述步骤的结果,构成阵列结构的第一分子层的π-电子共轭分子具有这样的构造:柔性侧链吸附到电极的表面并且盘状骨架定向平行并粘附到 电极的表面。 构成阵列结构的第二和随后的分子层的打桩方向由pi-pi相互作用控制。

    • 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).
    • 功能分子元素,其功能可以通过电场控制,基于新的原理。 通过可以作为路易斯酸的金属离子(3)以键状形式在键上设置在分子的长轴方向上具有正介电常数各向异性或偶极矩的路易斯碱分子(14) 分子(2)以具有共轭体系的线或膜的形式表现出导电性,从而形成能够实现构象由于施加电场而变化的功能的功能分子元件1。 导电键分子(2)和路易斯碱分子(14)与金属离子(3)形成络合物。 当在垂直于图1中的纸平面的方向上施加电场时, 如图1(b)所示,例如,路易斯碱分子(14)以图中的上下方向为轴进行90°的“颈部扭转”运动。 此外,如图所示,当在图中的上下方向上施加电场时, 如图1(c)所示,路易斯碱分子(14)以垂直于纸面的方向作为轴进行“跷跷板”运动,从而切换导电键分子(2)的导电性。
