A Metal–Organic Framework-Based Material for Electrochemical Sensing of Carbon Dioxide
Gassensmith, Jeremiah J.,Kim, Jeung Yoon,Holcroft, James M.,Farha, Omar K.,Stoddart, J. Fraser,Hupp, Joseph T.,Jeong, Nak Cheon American Chemical Society 2014 JOURNAL OF THE AMERICAN CHEMICAL SOCIETY - Vol.136 No.23
<P>The free primary hydroxyl groups in the metal–organic framework of CDMOF-2, an extended cubic structure containing units of six γ-cyclodextrin tori linked together in cube-like fashion by rubidium ions, has been shown to react with gaseous CO<SUB>2</SUB> to form alkyl carbonate functions. The dynamic covalent carbon–oxygen bond, associated with this chemisorption process, releases CO<SUB>2</SUB> at low activation energies. As a result of this dynamic covalent chemistry going on inside a metal–organic framework, CO<SUB>2</SUB> can be detected selectively in the atmosphere by electrochemical impedance spectroscopy. The “as-synthesized” CDMOF-2 which exhibits high proton conductivity in pore-filling methanolic media, displays a ∼550-fold decrease in its ionic conductivity on binding CO<SUB>2</SUB>. This fundamental property has been exploited to create a sensor capable of measuring CO<SUB>2</SUB> concentrations quantitatively even in the presence of ambient oxygen.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/jacsat/2014/jacsat.2014.136.issue-23/ja5006465/production/images/medium/ja-2014-006465_0006.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/ja5006465'>ACS Electronic Supporting Info</A></P>
