单层多臂结（mAJ）基序在二维平面晶格、三维曲面多面体、三维线框结构和张拉整体结构中得到了广泛的研究。在此，我们报告了编织策略，以实现3AJ2和4AJ2的两层堆叠的多臂结瓦片（缩写为mAJ2），以及纳米笼和2D菱形晶格的几个主要镶嵌纳米结构，其携带精美的浮雕4点星。完美镶嵌的挑战也提出了关于从2D到3D的图案复杂性的增加。
One-layer multi-arm junction (mAJ) motifs have been investigated extensively for many kinds of planar 2D (two-dimension) lattices, surface-curved 3D (three-dimension) polyhedra, and complex 3D wireframe and tensegrity structures. Herein, we report the weaving strategy to achieve two-layer stacked multi-arm junction tiles (abbreviated as mAJ2) of 3AJ2 and 4AJ2, and several primary tessellation nanostructures of nanocages and 2D rhombus lattices carrying beautifully embossed 4-point stars. Challenges for perfect tessellation are also raised regarding the increase of motif complexity from 2D to 3D.
