A novel anthracene-modified metal–organic framework, [Cu2(ADEDA)(H2O)2]·4DMF (compound 1) (H4ADEDA = 5,5′-(anthracene-9,10-diylbis(ethyne-2,1-diyl))diisophthalic acid), has been successfully synthesized under solvothermal conditions. Structural analysis shows that the framework of compound 1 is built up with binary structural units composed of a classical [Cu2(CO2)4] paddle-wheel and a 3-linked expanded tetracarboxylates ligand. The entire three-dimensional framework possesses a (3,4,4)-connected fof topology. On the basis of the functional anthracene groups and the large pore volume, compound 1 can effectively adsorb cationic dyes such as methylene blue (MLB), methyl violet(MV), rhodamine 6G (Rh6G), and the neutral dye neutral red (NR), but exclude anionic dyes such as methyl orange (MO) and orange II. With the functional anthracene groups and the large pore volume, compound 1 can effectively adsorb cationic dyes, such as MLB, MV, Rh6G, and the neutral dye NR, but exclude anionic dyes such as MO and orange II. Furthermore, compound 1 has size rejection capabilities for various dye molecules, and the amount of adsorption declines with the increasing dye size. Compound 1 is capable of efficiently and selectively adsorbing the cationic dye MLB for mixed MO and MLB and orange II and MLB. Given above, compound 1 should be a promising MOF material for the adsorption and separation of organic dyes.

具有 fof 拓扑结构的蒽修饰金属-有机骨架用于有机染料的高效吸附和分离
一种新型蒽修饰的金属有机骨架，[Cu 2 (ADEDA)(H 2 O) 2 ]·4DMF (compound 1 ) (H 4 ADEDA = 5,5'-(anthracene-9,10-diylbis(ethyne- 2,1-二基））二间苯二甲酸）已在溶剂热条件下成功合成。结构分析表明，化合物1的骨架由经典的[Cu 2 (CO 2 ) 4 ]桨轮和三联扩展四羧酸酯配体组成的二元结构单元构成。整个三维框架具有（3,4,4）连接的fof拓扑。基于功能性蒽基团和大孔体积，化合物1可有效吸附亚甲蓝（MLB）、甲基紫（MV）、罗丹明6G（Rh6G）等阳离子染料，以及中性染料中性红（NR），但不包括甲基橙（MO）、橙II等阴离子染料. 化合物1具有功能性蒽基团和大孔容，可以有效吸附MLB、MV、Rh6G等阳离子染料和中性染料NR，但不能吸附MO、orange II等阴离子染料。此外，化合物1对各种染料分子具有尺寸排斥能力，吸附量随着染料尺寸的增加而下降。化合物1能够高效选择性地吸附阳离子染料 MLB，用于混合 MO 和 MLB 以及橙色 II 和 MLB。上面给出，化合物1应该是一种很有前途的MOF材料，用于吸附和分离有机染料。
