Abstract
- The organometallic cation 1 (Fe(bipy-NH <subscript>2</subscript> ) <subscript>3</subscript> <superscript>2+</superscript> , bipy-NH <subscript>2</subscript> = 4,4'-diamino-2,2'-bipyridine), which was constructed in situ in solution, can bind CO <subscript>2</subscript> from air effectively with a stoichiometric ratio of 1:4 (1/CO <subscript>2</subscript> ), through the formation of "H-bonded CO <subscript>2</subscript> " species: [CO <subscript>2</subscript> -OH-CO <subscript>2</subscript> ] <superscript>-</superscript> and [CO <subscript>2</subscript> -CO <subscript>2</subscript> -OH] <superscript>-</superscript> . These two species, along with the captured individual CO <subscript>2</subscript> molecules, connected 1 into a novel 3D (three-dimensional) architecture, that was crystal 1·2(OH <superscript>-</superscript> )·4(CO <subscript>2</subscript> ). The adsorption isotherms, recycling investigations, and the heat capacity of 1 have been investigated; the results revealed that the organometallic cation 1 can be recycled at least 10 times for the real-world CO <subscript>2</subscript> capture applications. The strategies presented here may provide new hints for the development of new alkanolamine-related absorbents or technologies for CO <subscript>2</subscript> capture and sequestration.
