The ordered array of nanovoids in nanoporous networks, such as honeycomb, Kagome, and square, provides a molecular template for the accommodation of "guest molecules". Compared with the commonly studied guest molecules featuring high symmetry evenly incorporated into the template, guest molecules featuring lower symmetry are rare to report. Herein, we report the formation of a distinct patterned superlattice of guest molecules by selective trapping of guest molecules into the honeycomb network of trimesic acid (TMA). Two distinct surface patterns have been achieved by the guest inclusion induced adaptive reconstruction of a 2D molecular nanoporous network. The honeycomb networks can synergetically tune the arrangement upon inclusion of the guest molecules with different core size but similar peripherals groups, resulting in a trihexagonal Kagome or triangular patterns.
纳米多孔网络（如蜂窝状、 Kagome 状和正方形）中有序排列的纳米空隙为“客体分子”的容纳提供了分子模板。与通常研究的具有高对称性且均匀纳入模板的客体分子相比，具有较低对称性的客体分子鲜有报道。在此，我们报告了通过将客体分子选择性捕获到均苯三甲酸（TMA）的蜂窝网络中形成独特图案化的客体分子超晶格。通过客体包合诱导的二维分子纳米多孔网络的自适应重构实现了两种不同的表面图案。蜂窝网络在包含具有不同核心尺寸但外围基团相似的客体分子时，可以协同调节排列，从而形成三六边形 Kagome 图案或三角形图案。
