The present invention relates to compounds capable of forming metal-organic frameworks (MOFs), particularly f-block metal MOFs which selectively sorb one component (e.g. para-xylene) from a mixture of components (e.g. m-/p-xylene mixture). The invention also relates to methods of producing and using said compounds.

In the design and construction of metal–organicframeworks (MOFs), the utilization of slim ligands is usually more inclined to form interpenetrated structures compared with bulky ones. The structural interpenetration can improve the framework stability and in some cases, enhance gasadsorption capacity and selectivity due to confined pores. In order to explore the structural control of MOFs and construct
在金属有机骨架(MOF)的设计和建造中,与庞大的配体相比,稀有配体的利用通常更倾向于形成互穿结构。结构上的互穿可以改善骨架的稳定性,并且在某些情况下,由于孔的限制,可以提高气体的吸附能力和选择性。为了探索MOF的结构控制并构建具有良好的选择性气体吸附能力的新型MOF,本文使用了一种基于乙炔基的稀疏4连接的羧酸配体4,4',4'',4''-(苯-1,2,4,5-四基四(乙炔-2,1-二基)乙四酸(H 4 BTEB)用于设计和构建MOF,希望它们具有互穿结构。与4个连接的明轮式Cu 2(COO)4结合使用和8个连接的Zr 6 O 4(OH)8(COO)8簇,BTEB 4−配体产生了两个新的MOF,即[Cu 2(BTEB)(H 2 O)2 ](BUT-43)和[Zr 6 O 4(OH)8(H 2 O)4(BTEB)2 ](BUT-44)。不出所料,这两个MOF具有带通道分隔的双重互穿框架结构。B
