在超高真空中通过模板法构建了以Sierpinski三角形为结构单元的晶体结构，并通过低温扫描隧道显微镜进行了研究。钴原子和4，4”-二氰基-1，1 '：3'，1”-三联苯分子用于构建Sierpinski三角形。使用Au（100）-（hex）、Au（111）-22 x root 3和阶梯状Au（111）表面作为模板来引导Sierpinski三角形的堆积。利用该方法在实验中成功地制备了一维双链和二维Sierpinski三角形小畴。
Crystalline structures with Sierpinski 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 Sierpinski triangles. The Au(100)-(hex), Au(111)-22 x root 3, and stepped Au(111) surfaces were used as templates to guide the packing of Sierpinski triangles. One-dimensional double chains and two-dimensional small domains of Sierpinski triangles were successfully prepared using the method in experiments.
