## Description

- description: Self-assembly processes are widely used in nature to form hierarchically
    organized structures, prompting us to investigate such processes at the macroscopic
    scale. We report an unprecedented approach toward the self-assembly of alkyl-fullerene
    (C60) derivatives into a hexagonal array of hemispherical microparticles akin
    to the morphology of a compound eye. The method includes casting solvated alkyl-C60
    compound on an air/water interface followed by controlled evaporation of the solvent
    under atmosphere-sealed conditions. This leads to the formation of a thin film
    floating on water with a diameter of up to 1.3 centimeters and exhibiting a hexagonally-packed
    hemispherical structure with a diameter of approximately 38 µm. Various measurements
    of the formed film reveal that amorphousness is necessary for suppressing uncontrollable
    crystallization, which affects the microparticle size and film formation mechanism.
    We tested the feasibility of this approach for the self-assembly of a relatively
    common C60 derivative, [6,6]-phenyl-C61-butyric acid methyl ester (PC61BM), resulting
    in the formation of a film with a similar pattern of hexagonally-packed larger
    microparticles approximately 152 µm in size of diameter.
