A new material, MOF-type [Ir]@NU-1000, was accessed from the incorporation of the iridium organometallic fragment [Ir{κ 3 (P,Si,Si)PhP( o -C 6 H 4 CH 2 Si i Pr 2 ) 2 }] 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 2 is significantly enhanced with respect to that of NU-1000. Being a highly promising adsorbent for SO 2 capture, [Ir]@NU-1000 combines exceptional SO 2 uptake at room temperature and outstanding cyclability. Additionally, it is stable and can be regenerated after SO 2 desorption at low temperature.
