A novel bis(m-phenylene)-32-crown-10 derivative bearing two π-extended pyridyl groups was synthesized, and its host-guest complexation with a paraquat derivative to form a threaded [2]pseudorotaxane was studied. Subsequently, a poly[2]pseudorotaxane was constructed with a metallosupramolecular polymer backbone via metal coordination, which was comprehensively confirmed by the combination of (1)H NMR, (31)P{(1)H} NMR, DOSY NMR, DLS, and EDX techniques.
一种新型的双（间-亚苯基）-32-冠-10 衍生物，带有两个π-扩展的吡啶基，被合成出来，并研究了其与对苯二铵衍生物形成螺旋[2]假轮烷的主客体络合作用。随后，通过金属配位作用，以金属超分子聚合物为骨架构建了聚[2]假轮烷，通过（1）H NMR、（31）P{（1）H} NMR、DOSY NMR、DLS 和 EDX 技术的结合，对其进行了全面的证实。
