The development of homochiral materials for the enantioselective detection and separation of chiral drugs is in high demand for the pharmaceutical industry. Herein, an anionic homochiral metal–organic framework (HMOF) with in situ generated [Me2NH2]+ counterions, [Me2NH2]2[Zn2(d-L)2(HCO2)(OH)]·5H2O}n (HMOF-1), was synthesized using a d-camphorate-derived enantiopure dicarboxylate ligand, 4,4′-[[(1R
用于手性药物的对映选择性检测和分离的纯手性材料的开发是制药行业的高需求。在此,一种阴离子纯手性金属有机骨架 (HMOF)原位产生 [Me 2 NH 2 ] +抗衡离子,[Me 2 NH 2 ] 2 [Zn 2 ( d -L) 2 (HCO 2 )(OH)] ·5H 2 O} n (HMOF- 1 ), 是使用d-樟脑酸酯衍生的对映纯二羧酸配体 4,4'-[[(1 R ,3 S)-1,2,2-trimethylcyclopentane-1,3-dicarbonyl]bis(azanediyl)]dibenzoic acid ( d -H 2 L) 通过简单的溶剂热法。有趣的是,HMOF- 1可用作母体框架,通过离子交换过程封装 Eu 3+阳离子,产生具有双发光中心的 Eu 3+ @HMOF - 1复合材料。得到的Eu 3+ @HMOF- 1在水中具有较高的化学稳定性和良好的发光稳定性。重要的是,Eu
