title: Direction control of oriented self-assembly for 1D, 2D, and 3D microarrays of anisotropic rectangular nanoblocks.
abstract: Micrometric linear chains (1D arrays), monolayers (2D arrays), and superstructures (3D arrays) of anisotropic Mn3O4 nanocuboids were selectively produced by oriented self-assembly through evaporation of a dispersion. The 1D arrays were basically formed on a substrate via oriented self-assembly of the rectangular crystals in the ⟨100⟩ direction. The 2D and 3D microarrays were obtained by adjusting the particle concentration of the dispersion. The [001] direction of tetragonal crystal was controlled to be parallel and perpendicular to the substrate by changing the polarity of the medium.
