Naphthalene-diimide (NDI)-containing nanocylinders were formed by supramolecular self-assembly in water through cooperative hydrogen bonds between bis(urea) units, reinforced by hydrophobic and aromatic-stacking interactions. The nanocylinders, decorated with poly(ethylene oxide) arms ensuring their solubility in water, exhibit a huge aspect ratio (diameter 13 nm, length 300 nm) and are extremely stable.
含萘二亚胺（NDI）的纳米圆柱体通过双（脲）单元之间的协同氢键在水中通过超分子自组装形成，并通过疏水和芳香堆积相互作用得到增强。用聚环氧乙烷臂修饰以确保其在水中的溶解性的纳米圆柱体具有巨大的纵横比（直径13纳米，长度300纳米）且极其稳定。
