Here, a bioinspired strategy is used to prepare well-ordered nanotubular structures, as observed in animals and plants, such as gecko toe pads or corals. The nanotubes are obtained by templateless electropolymerization of thieno[3,4-]thiophene-based monomers with various aromatic groups in an organic solvent (dichloromethane). The most interesting and robust structures were obtained with carbazole and pyrene substituents to the base monomer structure, since these groups participate significantly in the polymerization and also have strong -stacking interactions. The addition of water to electropolymerization solvent significantly impacted the formation of nanotubes, as it caused the release of a significant amount of H and O bubbles, depending on the electropolymerization method. Identifying templateless approaches to vary nanotubular structures is very interesting, as these materials are sought-after for applications in water harvesting systems. This article is part of the theme issue 'Bioinspired materials and surfaces for green science and technology (part 3)'.
在这里，我们采用一种受生物启发的策略来制备具有规则纳米管状结构的材料，这些结构存在于动物和植物中，例如壁虎的脚趾垫或珊瑚。通过无模板电聚合基于噻吩[3,4-b]噻吩的单体，在有机溶剂（二氯甲烷）中获得了纳米管。带有咔唑和并五苯取代基的单体结构得到了最有趣和最稳定的结构，因为这些基团显著参与了聚合反应，并且具有很强的π-π堆积相互作用。向电聚合溶剂中添加水会显著影响纳米管的形成，因为这会导致大量 H 和 O 气泡的释放，具体取决于电聚合方法。确定无模板方法来改变纳米管状结构是非常有趣的，因为这些材料在用于水收集系统的应用中受到了广泛关注。本文是主题为“绿色科学技术的仿生材料和表面（第 3 部分）”的一部分。
