isomers, or even a mixture of them, is present in the solution. A prime matching between the size and shape of the dication and the formed dianions plays a key role in enabling the selective self‐assembly, as proven by successful encapsulation of halogen‐bond donors as weak as 1,4‐dichlorobenzene and by the results of cocrystallization trials involving mismatching tectons. Encapsulated para‐dihalobenzenes
二碘化癸报告执行的化疗和区域选择性的封装对通过竞争从形成的解决方案,也含有起始卤素键合的共结晶的-dihalobenzenes邻位和间位异构体。即使溶液中存在过量的邻位或间位异构体,或什至它们的混合物,也会发生固体中的选择性笼蔽。药物大小和形状以及所形成的二价阴离子之间的主要匹配在实现选择性自组装中起着关键作用,成功地封装了弱至1,4-二氯苯的卤素键供体,并得到了结果证明了这一点。共晶试验涉及不匹配的构造。封装的对二卤代苯的客体分子可以通过在减压下加热共晶体来定量除去,并作为纯物质回收。残留的十碘化二碘甲烷可以循环使用而不会降低选择性。
