on the improved versatility of helical polycarbodiimides capable of undergoing low energy reversible conformational changes from realignment of their restricted polyarene pendant groups has led to seven new polycarbodiimides that each present unique information in regards to how the electronics and connectivity of the arene π‐system play a crucial role in the behavior of these polymers.

螺旋聚碳二亚胺能够通过限制的聚芳烃侧基的重排而进行低能可逆构象变化的多功能性的最新发现,导致了七个新的聚碳二亚胺,每个聚碳二亚胺都提供了有关芳烃π系统的电子学和连通性的独特信息在这些聚合物的行为中起着至关重要的作用。除了它们各自的异常行为外,这一系列功能性聚合物还为全球理解这一复杂开关过程背后的控制力开辟了新的答案。通过结合共价附于萘侧基的官能团,实现了这些系统的显着变化和新应用。可变温度极化法用于观察这些手性聚合物的可逆构象变化。©2010 Wiley Periodicals,Inc. J Polym Sci A部分:Polym Chem,2011年
