Polymers obtained by on-surface chemistry have emerged as a class of promising materials. Here, we propose a new strategy to obtain self-assembled 1D polymers by using photochemical [2+2] cyclo-addition or by using a mild thermal annealing. All nanostructures are fully characterized by using scanning tunneling microscopy at ambient conditions on a graphite surface. We demonstrated that nature of the stimulus strongly alters the overall quality of the resulting polymers in terms of length and number of defects. This new way is an efficient method to elaborate on-surface self-assembled 1D polymers.
通过表面化学获得的聚合物已成为一类有前途的材料。在此，我们提出一种新策略，通过光化学[2+2]环加成或温和的热退火来获得自组装的一维聚合物。所有纳米结构都通过在石墨表面的环境条件下使用扫描隧道显微镜进行了全面表征。我们证明，刺激的性质在聚合物的长度和缺陷数量方面强烈改变了所得聚合物的整体质量。这种新方法是制备表面自组装一维聚合物的有效方法。
