| 摘要: 通过使用不同尺寸的辅配体，我们合成了一系列以二价镍为金属离子，蒽醌四羧酸为主配体的金属有机框架化合物（1~5）。根据微相分离理论，通过选用不同尺寸的辅配体来调节聚合物的疏水体积比，我们得到具有不同结构的一系列配位聚合物。实验结果表明，化合物1和2表现为简单的二维层状结构，化合物3和4具有准三维结构，化合物5则具有三重穿插的二维结构。实验结果与微相分离理论所预测的结果相吻合。 |

| Abstract: By using secondary ligands of different sizes, we prepared a series of MOFs (complexes 1~5) based on Ni(Ⅱ) as metal iron and anthraquinone-1,4,5,8-tetracarboxylic acid (H4AQTC) as the main ligand. According to Micro-phase Separation Theory, these coordination polymers are hypothesized to show different structures because of their different hydrophobic volume ratio, which was actually adjusted by the secondary ligands. Our results showed that complexes 1 and 2 revealed simple 2-dimensional layered structure, while complexes 3 and 4 produced quasi-3-dimensional structure. Complex 5 possessed a 2-dimensinal structure with 3-fold interpenetrating pattern. Therefore in our cases, the experimental data is consistent with the prediction of Micro-phase Separation Theory.
