By adding 4,4′-bipyridine (BPY) to cross-link the paddle-wheel clusters M₂(–COO)₄L₂, isoreticular metal–organic frameworks (MOFs) have been constructed from a flexible tritopic linker, 4,4′,4′′-s-triazine-1,3,5-triyltri-p-aminobenzoic acid (H₃TATAB), termed as ST-14 [Cu₆(TATAB)₄(BPY)₃] and ST-15 [Zn₆(TATAB)₄(BPY)₃]. With a secondary-amine group, these MOFs have shown exculsive cationic dye capture properties with charge selectivity, metal-dependent adsorption kinetics, and solvent-dependent dye release. This work sheds light on further designing smart porous materials for drug delivery, molecular inclusion, sensing and so on.

仲胺官能化的等孔金属-有机框架，用于可控和选择性的染料捕获†

通过添加4,4'-联吡啶（BPY）交联桨轮簇M ₂（–COO）₄ L ₂，已经从柔性三位连接体4,4构造了等孔金属-有机骨架（MOF）。 '，4'' -小号嗪-1,3,5- triyltri- p氨基苯甲酸（H ₃ TATAB），称为ST-14 [铜₆（TATAB）₄（BPY）₃ ]和ST-15 [锌₆（TATAB）₄（BPY）₃]。这些MOF具有仲胺基，具有电荷选择性，金属依赖性的吸附动力学和溶剂依赖性的染料释放性，显示出具有控制性的阳离子染料捕获性能。这项工作为进一步设计用于药物输送，分子包涵，传感等的智能多孔材料提供了启示。
