Crystalline structures with Sierpiński triangles as building blocks were constructed via a templating method in an ultra-high vacuum and studied by low-temperature scanning tunneling microscopy. Cobalt atoms and 4,4''-dicyano-1,1':3',1''-terphenyl molecules were used to build the Sierpiński triangles. The Au(100)-(hex), Au(111)-22 ×, and stepped Au(111) surfaces were used as templates to guide the packing of Sierpiński triangles. One-dimensional double chains and two-dimensional small domains of Sierpiński triangles were successfully prepared using the method in experiments.
以谢尔宾斯基三角形为构建单元的晶体结构通过超高真空下的模板法构建，并利用低温扫描隧道显微镜进行研究。钴原子和4,4''-二氰基-1,1':3',1''-三联苯分子被用于构建谢尔宾斯基三角形。Au(100)-(六方)、Au(111)-22×和阶梯状Au(111)表面被用作模板来引导谢尔宾斯基三角形的堆积。实验中使用该方法成功制备了一维双链和二维小尺寸的谢尔宾斯基三角形区域。
