Fractals are of fundamental importance in science and technology. Theoretical simulations indicate that Sierpiński triangles (STs) possess specific optical and electronic properties. To study their properties and uncover their potential applications, it is necessary to pack STs into large-scale two-dimensional crystalline structures. Here, a series of ordered structures consisting of ST units are successfully constructed on gold surfaces through coordination between 1,3-bis(4-pyridyl) benzene molecules and Fe atoms. Crystals of STs are characterized by scanning tunneling microscopy. K-map analysis explains the structural formation mechanism, which is further verified by density functional theory calculations. The molecular free diffusion and nice structure matching between STs and gold surfaces play important roles in the formation of crystals of STs.

将谢尔宾斯基三角形包装成二维晶体

分形在科学和技术中具有根本的重要性。理论模拟表明谢尔宾斯基三角形 (ST) 具有特定的光学和电子特性。为了研究它们的性质并揭示它们的潜在应用，有必要将 ST 封装成大规模的二维晶体结构。在这里，通过1,3-双(4-吡啶基)苯分子和Fe原子之间的配位，在金表面成功构建了一系列由ST单元组成的有序结构。STs 晶体的特征在于扫描隧道显微镜。K-map分析解释了结构形成机制，密度泛函理论计算进一步验证了这一点。
