The Topochemical 1,6-Polymerization of a Triene

The first topochemical 1,6-polymerization of a triene has been observed. The required supramolecular structure for this polymerization was achieved by the π−π stacking of the isonicotinate functionality. The crystal environment of this polymerization reaction controlled both the molecular and supramolecular structure of the polymer and allowed its structure to be determined by single-crystal X-ray diffraction.

本研究首次观测到三烯的拓扑化学1,6-聚合反应。该聚合反应所需的超分子结构，通过异烟酸酯官能团的π-π堆积作用得以实现。此聚合反应的晶体微环境同时调控了聚合物的分子结构与超分子结构，并使得其结构可通过单晶X射线衍射法完成解析。
