Recent investigations of supramolecular polymers based on chiral triphenylene-2,6,10-tricarboxamides (TTAs) showed how temperature-induced changes in solvation can greatly influence the preferred helical conformation of the supramolecular polymers formed. Here, we combine chiral TTA with achiral copolymerization partners to further investigate temperature-dependent solvation effects. Systematic variation of the system's composition shows clear impacts on the temperature window where the conformational change occurs. Further, simple chain length variations in the achiral comonomer greatly affect the ability to influence the conformational change in the copolymer, while the differences in the properties of the individual homopolymers are rather small. We herein highlight how subtle changes in the monomers can impact the observed copolymer properties drastically; an effect arising from the emerging complexity of multicomponent interactions in supramolecular copolymers with solvent-solute interactions being more important than typically thought.

手性和超分子共聚——微妙溶剂化效应的难以捉摸的作用

最近对基于手性三亚苯基-2,6,10-三甲酰胺 (TTA) 的超分子聚合物的研究表明，温度引起的溶剂化变化如何极大地影响所形成的超分子聚合物的首选螺旋构象。在这里，我们将手性 TTA 与非手性共聚伙伴相结合，以进一步研究温度依赖性溶剂化效应。系统组成的系统变化显示出对发生构象变化的温度窗口的明显影响。此外，非手性共聚单体中简单的链长变化极大地影响了影响共聚物中构象变化的能力，而单个均聚物的性能差异相当小。我们在此强调单体的细微变化如何显着影响观察到的共聚物性能；一种由超分子共聚物中多组分相互作用的新兴复杂性产生的影响，其中溶剂 - 溶质相互作用比通常认为的更重要。
