哪位大虾有看到过UI0-66的合成方法如下所示： 1.025g ZrCl4 + 0.655g H2BDC +50ml DMF, 小弟曾经见过这篇文献，忘记下载下来了，现在怎么找都找不到了。 |

Synthesis All chemicals were obtained commercially (Aldrich) and used without further purification. Standard synthesis of Zr‐BDC MOF was performed by dissolving ZrCl4 (0.053 g, 0.227 mmol) and 1,4‐benzenedicarboxylic acid (H2BDC) (0.034g, 0.227 mmol) in N,N`‐ dimethylformamide (DMF) (24.9 g, 340 mmol) at room temperature. The thus obtained mixture was sealed and placed in a pre‐heated oven at 120 ˚C for 24 hours. Crystallization was carried out under static conditions. After cooling in air to room temperature the resulting solid was filtered, repeatedly washed with DMF and dried at room temperature. Zr‐BDC can be obtained when varying the H2BDC/ZrCl4 ratio from 0.5 to 3 and when tripling the reactant concentration. The Zr‐BPDC and Zr‐BPDC MOFs are synthesized by replacing BDC with equivalent molar amounts of the longer linkers. |
