Structural analysis of the designed 2D assembly 2D-HBN. (A) Lattice design of 2D-HBN, and its designed interface with a hydrogen bond network (B). (C) Negatively stained array of 2D-HBN showing an extensive and flexible 2D assembly. (D) AFM image of 2D-HBN assemblies, with a zoomed-in view of one of the assemblies superimposed onto the design model (E). (F) AFM height profiles of 2D-HBN assemblies. (G) Thickness of the design model is 2.3 nm based on Cβ distances. (H) In situ self-assembly of 2D-HBN, red circles show regions of growth at t = 0 min (dotted) and t = 10 min (solid). Inset, zoomed-in view of one of the growing assemblies. All scale bars: white, 50 nm; black, 5 nm.
