    AnotaceMolecular electronics aims at use of molecules as the working components (wires, diodes, transistors, and logic and memory
    elements) of the future electronic devices. It represents an alternative to the solid-state semiconductor technologies, which will
    soon reach their miniaturization limits. Naturally, studies of electrical properties of molecules at the single molecule level represent
    the cornerstone in the development of molecular electronic devices. The invention of the scanning tunneling microscope (STM) by
    Gerd Binnig and Heinrich Rohrer (Nobel Prize in Physics in 1986) and of the atomic force microscope (AFM) by Gerd Binnig,
    Calvin Quate, and Christoph Gerber enabled to overcome the experimental barrier for direct visualization of individual molecules
    and promoted the evaluation of their properties at the single molecule level.
    Molecular electronic components typically consist of a backbone capped by two termini-anchors to provide contact with
    two electrodes. Examples of anchoring groups include thiol, pyridine, nitrile, amine, or fullerene. Passive components
    (molecular wires and resistors) possess no functionality in the backbone. Active ones, such as molecular diodes or
    switches, contain additional moiety that provides desired functionality. Current rectification in molecular diodes may be
    for example attained by an asymmetric arrangement of side groups with a different inductive effect. Molecular switches
    contain a moiety with two chemically stable states. These states are switched by an external trigger such as illumination
    (photoswitches), local environment (pH and ligand-driven switches), pressure (mechanical switches), or electrode potential
    (redox switches).
