a TC-1-1; b TC-1-2; c TC-2-1; d TC-2-2; e TC-3-1; f TC-3-2; g TC-4-1; h TC-4-2. Each figure contains the design of tile, cylindrical model of tile (side view and 3D view) and AFM images of assembled arrays. The dash lines in a side view indicate the layers of tiles. For the sticky-end matching rules, a pair of complementary sticky ends are labeled as Sn and Sn* (n is a number), and a T-loop sticky-end interaction is marked as Bn (sticky end) and Bn* (T-loop). Each pair of complementary sticky ends or interaction between a T-loop and a sticky end is given a unique color identifier. A self-complementary sticky end is denoted as Sn. All the tiles labeled as Tile n-1 target ladders, while Tile n-2 target 2D grids. All the AFM images are taken after 66 h annealing program. Inset image size: 100 nm × 100 nm. Source data are provided as a Source Data file.
