A new
material, MOF-type [Ir]@NU-1000, was accessed from the incorporation
of the iridium organometallic fragment [Ir{κ3(P,Si,Si)PhP(o-C6H4CH2Si
i
Pr2)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 SO2 is
significantly enhanced with respect to that of NU-1000. Being a highly
promising adsorbent for SO2 capture, [Ir]@NU-1000 combines
exceptional SO2 uptake at room temperature and outstanding
cyclability. Additionally, it is stable and can be regenerated after
SO2 desorption at low temperature.
Herein we report an experimental and computational study of a family of four coordinated 14-electron complexes of Rh(III) devoid of agostic interactions. The complexes [X-Rh(κ3(P,Si,Si)PhP(o-C6H4CH2SiiPr2)2], where X = Cl (Rh-1),...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
