A Microporous Metal–Organic Framework for Gas-Chromatographic Separation of Alkanes


  • This work was supported by the University of Texas-Pan American through a Faculty Research Council award to B.C., by the Welch Foundation grant (BG-0017) to the Department of Chemistry at UTPA, by an appointment to the Higher Education Research Experiences (HERE) at the Oak Ridge National Laboratory (ORNL) for faculty (B.C.), which is sponsored by the US Department of Energy and administered by the Oak Ridge Institute for Science and Education, and by the Office of Basic Energy Sciences, US Department of Energy, under contract No. DE-AC05-00OR22725 with UT-Battelle, LLC (S.D.). We thank Dr. Jing-Feng Huang for his help with the GC separation of alkanes.

Filling the pores: A zinc-based metal–organic framework (MOF) can be transformed reversibly from an open (a) to a dense (b) configuration. The microporous solid is the first example of a MOF that is highly selective in the gas-chromatographic separation of alkanes.
