本文报道了一种新型的带负电荷的微孔金属有机骨架材料[（C_2H_5）（2）NH_2]（2）[Mn-6（L）（OH）（2）（H_2O）（6）]中心点4DEF（1）。（H12 L = 5，5 ′，5 ″，5 ″ ′，5 ″ ″，5 ″ ″ ′-[1，2，3，4，5，6-苯基六甲氧基]六异邻苯二甲酸和DEF = N，N '-二乙基甲酰胺），以及其作为通过离子交换过程高选择性吸附和分离有机染料的平台的用途。一系列有机染料的选择性吸附、分离和释放动力学研究表明，这种基于交换的分离过程与有机染料的尺寸或电荷高度相关，这种关系可以通过MOF 1的结构特征来控制。
We report a new microporous negatively charged metal-organic framework (MOF), [(C2H5)(2)NH2](2)[Mn-6(L)(OH)(2)(H2O)(6)]center dot 4DEF (1) (H12L = 5,5 ',5",5"',5"",5""'-[1,2,3,4,5,6-phenylhexamethoxyl] hexaisophthalic acid and DEF = N,N'-diethylformamide), and its utilization as a platform for the highly selective adsorption and separation of organic dyes through an ion-exchange process. The dynamics of selective adsorption, separation and re[ease of a series of organic dyes demonstrated that this exchange-based separation process is highly related to the sizes or charges of organic dyes, and this relationship can be controlled by the structural characteristics of MOF 1.
