It is still an enormous challenge to obtain the metal-organic frameworks (MOFs) with specific properties by tuning their structures. Here we first reported that the structures of MOFs could be tuned by adding certain amount of zwitterion pyridiniumolate. To demonstrate the inductive effect, two series of assembly experiments were performed using different metal ions, namely, Cd(II) and Mn(II). The experimental results revealed that the zwitterion pyridiniumloate only acted as a structural induction agent (SIA), which did not exist in the aimed compounds. The SIAs could effectively tune the framework aperture or promote coordination and further tune the properties of MOFs without any removal or exchange after the synthesis. Therefore, the results could not only immensely expand the syntheses and structural diversity of MOFs with the fixed metal ions and organic ligands but also afford the possibility and effective convenience for tuning the properties of MOFs in the functional material research fields.
通过调整金属有机框架（MOFs）的结构来获得具有特定性质的MOFs仍然是一个巨大的挑战。在此，我们首次报道了可以通过添加一定量的两性离子吡啶醇盐来调整MOFs的结构。为了证明诱导效应，使用不同的金属离子，即Cd(II)和Mn(II)进行了两组组装实验。实验结果表明，两性离子吡啶醇盐仅作为结构诱导剂（SIA），其并不存在于目标化合物中。这些SIA可以有效地调整框架孔径或促进配位，并在合成后无需任何去除或交换操作即可进一步调整MOFs的性质。因此，这些结果不仅可以极大地扩展具有固定金属离子和有机配体的MOFs的合成方法和结构多样性，而且为功能材料研究领域中调整MOFs的性质提供了可能性和有效的便利。
