Description:
Diamond lattices formed by atomic or colloidal elements exhibit remarkable functional properties. However, building such structures via self-assembly has proven to be challenging because of the low packing fraction, sensitivity to bond orientation, and local heterogeneity. We report a strategy for creating a diamond superlattice of nano-objects via self-assembly and demonstrate its experimental realization by assembling two variant diamond lattices, one with and one without atomic analogs. Our approach relies on the association between anisotropic particles with well-defined tetravalent binding topology and isotropic particles. The constrained packing of triangular binding footprints of truncated tetrahedra on a sphere defines a unique three-dimensional lattice. Hence, the diamond self-assembly problem is solved via its mapping onto two-dimensional triangular packing on the surface of isotropic spherical particles.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Liu, Wenyan -- Tagawa, Miho -- Xin, Huolin L -- Wang, Tong -- Emamy, Hamed -- Li, Huilin -- Yager, Kevin G -- Starr, Francis W -- Tkachenko, Alexei V -- Gang, Oleg -- AG029979/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 2016 Feb 5;351(6273):582-6. doi: 10.1126/science.aad2080.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Functional Nanomaterials, Brookhaven National Laboratory, Upton, NY 11973, USA. ; Department of Materials Science and Engineering, Nagoya University, Furo-cho, Chikusa-ku, Nagoya 464-8603, Japan. ; Biology Department, Brookhaven National Laboratory, Upton, NY 11973, USA. ; Department of Physics, Wesleyan University, Middletown, CT 06459, USA. ; Biology Department, Brookhaven National Laboratory, Upton, NY 11973, USA.
