Herein, we present a new strategy to design metal-organic frameworks (MOFs) as adsorbents for ammonia (NH) vapour. The linking ligand is functionalized with a sterically hindered Lewis acidic boron (B) centre, allowing efficient capture of NH and easy recycling of the MOF by simply heating at low temperature. The recycled MOF material can be used for NH capture for at least 5 cycles without losing its crystallinity or its luminescence properties.
在此，我们提出了一种新策略，设计金属有机框架（MOF）作为氨（NH₃）蒸气的吸附剂。连接配体用空间位阻路易斯酸性硼（B）中心进行功能化，允许高效捕获NH₃，并通过在低温下简单加热实现MOF的轻松回收。回收的MOF材料可用于NH₃捕获至少5个循环，而不会失去其结晶度或发光特性。
