Carbon nanotubes and graphene are outstanding materials of the 21st century with a broad spectrum of applications. However, major challenges are faced such as the intrinsically low solubility of both sp2 carbon allotropes. To overcome this hurdle the potential of noncovalent functionalization is summarized with a special focus on the establishment of the perylene bisimide unit as aromatic anchor to the graphitic surface. Rational surfactant design is unmasked as the key to solubilization of the carbon allotropes, while at the same time tailoring their surface properties, or even electronic properties in a fully reversible fashion.
碳纳米管和石墨烯是 21 世纪具有广泛应用前景的杰出材料。然而，它们都面临着固有低溶解度的重大挑战。为了克服这一障碍，本文总结了非共价功能化的潜力，特别关注了将苝二酰亚胺单元作为芳香锚定到石墨表面的方法。合理的表面活性剂设计被揭示为碳同素异形体溶解的关键，同时可以调整它们的表面性质，甚至以完全可逆的方式调整其电子性质。
