Abstract In this original work, we want to control the shape of the resulting porous structures by templateless electropolymerization, by adjusting the spacer (flexible alkyl chains or rigid aromatic groups) between thieno[3,4-b]thiophene and carbazole used as the monomer and the substituent, respectively. A huge change is especially observed from ribbon-like structures to nanorings as the alkyl spacer increases. The presence of a significant amount of water is necessary for the formation of these porous structures because it allows releasing a high amount of gas bubbles. The size and number of nanorings are dependent on both the alkyl spacer and electrochemical parameters such as the number of deposition scans. These surfaces could be used in the future in various potential applications such as in water harvesting, oil/water separation membranes, optical devices, sensors or photocatalysis.

间隔基对无模板电聚合形成纳米环的影响

摘要 在这项原始工作中，我们希望通过无模板电聚合控制所得多孔结构的形状，通过调节噻吩并 [3,4-b] 噻吩和咔唑之间的间隔基（柔性烷基链或刚性芳基）作为单体和取代基，分别。随着烷基间隔物的增加，从带状结构到纳米环的巨大变化尤为明显。大量水的存在对于形成这些多孔结构是必要的，因为它允许释放大量气泡。纳米环的大小和数量取决于烷基间隔基和电化学参数，例如沉积扫描次数。这些表面将来可用于各种潜在应用，例如集水、油/水分离膜、
