探索了非常规氢键和卤素键在超分子聚合物形成中的协同作用。特别地，1-溴-2,3,5,6-四氟苯或1,2,4,5-四氟-3-碘苯与每个联吡啶基4,4'-联吡啶、反式-1,2-双(4-吡啶基)乙烯和1,2-双(4-吡啶基)乙炔的共结晶导致形成 线性超分子聚合物，其中两种组分通过协同交替的非常规 sp2-CH…N 氢键和卤素键连接在一起。
The role of cooperative nonconventional hydrogen bonding and halogen bonding in the formation of supramolecular polymers is explored. In particular, the cocrystallization of 1-bromo-2,3,5,6-tetrafluorobenzene, or 1,2,4,5-tetrafluoro-3-iodobenzene, with each of the dipyridyls 4,4′-bipyridine, trans-1,2-bis(4-pyridyl)ethene, and 1,2-bis(4-pyridyl)ethyne results in the formation of linear supramolecular polymers in which the two components are held together by cooperative alternating nonconventional sp2-CH···N hydrogen bonds and halogen bonds.
