A series of phenylene vinylene macrocycles (PVMs) bearing substituents with various sizes and electronic properties have been synthesized through a one‐step acyclic diene metathesis macrocyclization approach and their aggregation behaviors have been investigated. In great contrast to the aggregation of the analogous phenylene ethynylene macrocycles, which aggregate only when substituted with electron‐withdrawing
通过一步非环二烯复分解大环化方法合成了一系列带有各种尺寸和电子性质的取代基的亚苯基亚乙烯基大环(PVM),并研究了它们的聚集行为。与仅在被吸电子基团取代时类似的亚苯基亚乙炔基大环的聚集形成鲜明对比的是,这些PVM均具有异常强的聚集性,而与取代基的给电子或吸电子特性无关。通过热力学和计算机建模研究进一步研究了PVM的异常聚集行为,这表明与最近提出的直接空间穿透相互作用模型(而不是polar /π模型)有很好的一致性。
