Abstract
Co-crystallization of C-propyl-pyrogallol[4]arene (PgC3) with 4,4′-bipyridine (bpy) in ethanol afforded a multi-component complex (PgC3) · 3(bpy) ·(EtOH) (1) that consists of a one-dimensional brick-wall framework, which was formed by four pyrogallol[4]arene molecules and two juxtaposed bpy molecules, entrapping two other bpy molecules as guests within each cavity. Heating a mixture of PgC3 and trans-1,2-bis-(4-pyridyl)ethylene (bpe) in an ethanol-water mixed solvent allowed the isolation of a multi-component complex (PgC3) ·(bpe) · 2(EtOH) ·(H2O) (2), which has a two-dimensional wave-like polymer structure with the bpe molecules embedded in the wave trough between two PgC3 molecules. Single-crystal X-ray crystallography was utilized to investigate the hydrogen bonding networks of the multi-component complexes 1 and 2.
摘要
C-丙基-对苯二酚[4]芳烃(PgC3)与4,4'-联吡啶(bpy)在乙醇中的共结晶得到了一个由四种对苯二酚[4]芳烃分子和两种并置的bpy分子形成的包含两种其他bpy分子作为每个空腔中的客体的由四种对苯二酚[4]芳烃分子和两种并置的bpy分子形成的一维砖墙框架的多组分配合物(PgC3)·3(bpy)·(EtOH)(1)。将PgC3和反式-1,2-双(4-吡啶基)乙烯(bpe)的混合物在乙醇-水混合溶剂中加热,得到了一个具有二维波浪形聚合物结构的多组分配合物(PgC3)·(bpe)·2(EtOH)·(H2O)(2),bpe分子嵌入在两个PgC3分子之间的波浪槽中。利用单晶X射线晶体学研究了多组分配合物1和2的氢键网络。
