Mathematics and art converge in the fractal forms that also abound in nature. We used molecular self-assembly to create a synthetic, nanometer-scale, Sierpinski hexagonal gasket. This nondendritic, perfectly self-similar fractal macromolecule is composed of bis-terpyridine building blocks that are bound together by coordination to 36 Ru and 6 Fe ions to form a nearly planar array of increasingly larger hexagons around a hollow center.
数学与艺术在自然界中也大量存在的分形形式中交汇。我们利用分子自组装创造了一种合成的、纳米级的谢尔宾斯基六边形垫圈。这种非树枝状、完美自相似的分形大分子由双三联吡啶结构单元组成，这些结构单元通过与36个钌离子和6个铁离子配位结合在一起，形成围绕中空中心的一系列越来越大的六边形的近乎平面的阵列。
