A novel porous metal–organic framework Cu-BCPPy based on a desymmetrized heterofunctional ligand 3,5-di(4-carboxyphenyl)pyridine has been successfully synthesized under solvothermal conditions. The framework possesses two sizes of 2D straight channels, which are constructed by one pair and three pairs of helixes, respectively. The distortion of the ligand leads to the structure exhibiting a new type of (3,6)-connected topology. According to the structural characteristic, Cu-BCPPy can effectively adsorb large carcinogenic organic dyes sudan III (SD III) and direct black 38 (DB 38) but exclude small molecular dyes. Hence, Cu-BCPPy exhibits effective and selective adsorption performance for the carcinogenic dye DB 38 on the equal proportional mixture dyes methyl orange (MO) and DB 38, fluorescein and DB 38, and basic red 2 (BR 2) and DB 38 with different sizes. In addition, Cu-BCPPy can be also provided with the characteristic of high iodine adsorption and release, which indicates that it is a promising candidate material for selectively adsorption and separation of many substances.

通过基于多螺旋链的金属-有机骨架高效选择性去除致癌染料和碘吸附和释放

在溶剂热条件下成功合成了一种基于去对称杂官能配体 3,5-二(4-羧基苯基)吡啶的新型多孔金属-有机骨架Cu-BCPPy。该框架具有两种尺寸的二维直通道，分别由一对和三对螺旋构成。配体的变形导致结构表现出一种新型的 (3,6) 连接拓扑。根据结构特点，Cu-BCPPy可以有效吸附大的致癌有机染料苏丹III（SD III）和直接黑38（DB 38），但不包括小分子染料。因此，Cu-BCPPy在等比例的混合染料甲基橙 (MO) 和 DB 38、荧光素和 DB 38 以及碱性红 2 (BR 2) 和 DB 38 上显示出对致癌染料 DB 38 的有效和选择性吸附性能。此外，Cu-BCPPy还可以提供高碘吸附和释放的特性，这表明它是一种有前途的选择性吸附和分离多种物质的候选材料。
