crystallography, which revealed racemic R and S isomers with planar chirality present in the crystal in a 1:1 ratio. These crown ether based struts serve as excellent organic ligands to bind with transition metal ions in the construction of MOFs: the crown ethers BPP34C10DA and NPP36C10DA in the presence of Zn(NO3)2⋅4 H2O afforded the MOF‐1001 and MOF‐1002 frameworks, respectively. The crystal structures of
为了将冠醚引入金属有机骨架(MOF)的支链中,已经开发了用于合成二羧酸二苯并[30] crown-10(DB30C10DA),二羧酸di-2,3-萘[30]的通用方法。 Crown-10(DN30C10DA),二羧酸双对亚苯基[34] crown-10(BPP34C10DA)和二羧酸1,5-萘对亚苯基[36] crown-10(NPP36C10DA)。这些新型冠醚不仅可以保留其母体冠醚的特征,因为它们可以1)结合阳离子客体,并且2)用作制备机械连锁分子(MIM)(例如链烷和轮烷)的模板,而且它们还提供了配位基与MOF中的辅助建筑单元(SBU)连接。BPP34C10DA与1,1'-二甲基-4,4'-联吡啶双(六氟磷酸盐)的结合行为(DMBP ⋅已经通过UV / Vis,荧光和NMR光谱技术研究了2 PF 6)。复杂DMBP的晶体上层建筑⋅ 2 PF 6 ⊂BPP34C10DA物通过X-射线晶
