Planar, terpyridine-based metal complexes with the Sierpiński triangular motif and alkylated corners undergo a second self-assembly event to give megastructural Sierpiński pyramids; assembly is driven by the facile lipophilic-lipophilic association of the alkyl moieties and complementary perfect fit of the triangular building blocks. Confirmation of the 3D, pyramidal structures was verified and supported by a combination of TEM, AFM, and multiscale simulation techniques.
具有 Sierpiński 三角形图案和烷基化角的平面三吡啶金属配合物会发生第二次自组装事件，从而形成超结构的 Sierpiński 金字塔；组装过程由烷基部分的易位-亲脂性相互作用以及三角形构建块的互补完美配合驱动。通过 TEM、AFM 和多尺度模拟技术的组合，对 3D 金字塔结构进行了验证和支持。
