通过四个bis(benzimidazolepyridyl)benzthiazolo[5,4-d]thiazole配体和四个锌(II)、铁(II)或钴(II)阳离子组成的交织分子格栅的组装,然后闭环烯烃歧化反应合成了一个分子所罗门键。核磁共振光谱、质谱学和X射线结晶学证实了双互锁拓扑结构,随后的脱金属提供了完全有机的所罗门连接。其中每个金属离子定义了两个配体链的交叉点,这表明交织的分子网格应该成为合理构建其他复杂拓扑结构的有用支架。
A molecular Solomon link was synthesized through the assembly of an interwoven molecular grid consisting of four bis(benzimidazolepyridyl)benzthiazolo[5,4-d]thiazole ligands and four zinc(II), iron(II), or cobalt(II) cations, followed by ring-closing olefin metathesis. NMR spectroscopy, mass spectrometry, and X-ray crystallography confirmed the doubly interlocked topology, and subsequent demetalation afforded the wholly organic Solomon link. The synthesis, in which each metal ion defines the crossing point of two ligand strands, suggests that interwoven molecular grids should be useful scaffolds for the rational construction of other topologically complex structures.
