新型叠氮基金属-有机框架化合物的合成及后修饰研究

Post-synthetic modification of a novel azide-functionalized metal-organic framework

作为一类高效的有机合成方法,点击反应已被广泛应用于金属-有机框架化合物(MOFs)的后修饰研究.本文设计、合成了一种含有单叠氮官能团的羧基配体,通过与Zr^(4+)进行自组装,成功构筑了一种新型的锆-金属有机框架化合物(Ui O-68-s Azide).进一步对其进行后修饰研究,结果表明,在维持骨架完整的条件下,点击反应能高效、定量进行,而且所生成的MOFs仍具有较高的比表面积和孔容.

As a kind of organic reactions with high efficiency, click reactions have been widely used in post-synthetic modification（PSM） of metal-organic frameworks（MOFs）. Herein, we report the synthesis and PSM of a novel azide tagged Zr-MOF, Ui O-68-s Azide. The azide groups in the pore surface were subjected to ＂click＂ reaction, achieving quantitative conversion and maintaining high surface area.
