## Description

- description: Numerous rod-like organic molecules self-organize into layered structures,
    as demonstrated in various systems, including smectic liquid crystals, micelles,
    and lipid bilayers, owing to side-by-side intermolecular interactions. These layered
    structures are of interest to another class of layered molecular assemblies in
    the solid state, namely, small-molecule organic semiconductors (OSCs). Many OSCs
    are composed of various π-electron cores substituted with flexible side chains.
    Layered-structure formation is important in OSC systems because it enables the
    production of aligned molecular layers interfaced with gate dielectric layers,
    which are used to fabricate high-performance organic thin-film transistors (OTFTs).
    Using these rod-shaped OSCs, we developed a technique for fabricating single-crystal
    thin films of uniform thickness at the molecular level by introducing a geometric
    frustration effect between the layers. We also selectively produced crystalline
    polymorphs with distinct herringbone packing motifs. By producing these layer-controlled
    films on the trap-minimized surface of gate insulators, we fabricated OTFTs exhibiting
    sharp on/off switching characteristics approaching the Boltzmann limit. In this
    paper, we introduce recent techniques for the rational design of organic semiconductors.
