A new material, MOF-type [Ir]@NU-1000, was accessed from the incorporation of the iridium organometallic fragment [Ir{κ(P,Si,Si)PhP(-CHCHSiPr)}] into NU-1000. The new material incorporates less than 1 wt % of Ir(III) (molar ratio Ir to NU-1000, 1:11), but the heat of adsorption for SO is significantly enhanced with respect to that of NU-1000. Being a highly promising adsorbent for SO capture, [Ir]@NU-1000 combines exceptional SO uptake at room temperature and outstanding cyclability. Additionally, it is stable and can be regenerated after SO desorption at low temperature.
一种新型材料，金属有机框架类型的[Ir]@NU - 1000，是通过将铱有机金属片段[Ir{κ(P,Si,Si)PhP(-CHCHSiPr)}]掺入NU - 1000中得到的。这种新材料中铱(III)的含量低于1 wt%（铱与NU - 1000的摩尔比为1:11），但相对于NU - 1000，其对SO的吸附热显著增强。作为一种极具前景的用于捕获SO的吸附剂，[Ir]@NU - 1000在室温下具有出色的SO吸附能力和优异的循环性能。此外，它很稳定，在低温下解吸SO后可以再生。
