合成了全甲基取代六元瓜环(Me12Q[6])与1,4-二噁烷的包结配合物并生长了晶体,通过单晶X-射线衍射方法进行了表征;该配合物形成了以Me12Q[6]为“胶囊体”、1,4-二噁烷为“胶囊”芯材、水分子为“胶囊盖”的“分子胶囊”结构,“分子胶囊”通过氢键自组装形成一维超分子链,而一维的超分子链通过Me12Q[6]端口的羰基氧原子与水分子之间的氢键作用横竖交错组成二维具有空洞结构的分子网。

The inclusion complex of all-methyl-substituted hexagonal guanidine ring (Me12Q [6]) and 1,4-dioxane was synthesized and the crystals were grown and characterized by single crystal X-ray diffraction. The complex formed The structure of “molecular capsule” with Me12Q [6] as “capsule body” and 1,4-dioxane as “capsule” core material with water molecule as “capsule cover” Molecular capsules "self-assemble through hydrogen bonding to form one-dimensional supramolecular chains, and the one-dimensional supramolecular chains cross each other vertically and horizontally through the hydrogen bond between the carbonyl oxygen atoms and the water molecules on the Me12Q [6] port to form a two-dimensional hollow structure The molecular network.
