## Description

- description: Distinct from inorganic 2D nanomaterials (e.g., graphene, MoS2, etc,),
    self-assembled organic 2D materials are significant due to the unique advantages
    of fine structure tunability and functionality. Electronically and photofunctionally-active
    compounds (e.g., pentacene, p-sexiphenyl) are highly attractive for applications
    but are limited by difficult handling and the existence of only a few native structures
    of the compounds. Here, it is shown that a p-sexiphenyl derivative incorporated
    into 2D multilamellar sheets with chromophores oriented in the layers exhibits
    a significant polarization of photoluminescence. Highly emissive, amphiphilic
    sexiphenyl with hydrophilic/hydrophobic groups self-assembles at air–water interface
    with chromophore orientation in the resulting films being controlled by monolayer
    compression. Large-area multilamellar structures with p-sexiphenyl chromophores
    highly oriented against the 2D plane are prepared by consecutive film transfers.
    The 2D sheets exhibit significant polarization of photoluminescence with polarization
    ratio 0.8 between orthogonal in-plane axes. Notably, multilamellar structures
    cannot be established for the same p-sexiphenyl using thermotropic processing
    thus emphasizing the importance of the 2D sheet multilayer synthesis process.
    Amphiphile design can be applied for the tailored synthesis of large-area multilayered
    2D sheets and used to construct highly efficient light-emitting devices.
