Abstract: "Metal-organic
framework-5 (MOF-5) of composition Zn4O(BDC)(3) (BDC =
1,4-benzenedicarboxylate)
with a cubic three-dimensional extended porous structure adsorbed hydrogen up
to 4.5 weight percent (17.2 hydrogen molecules per formula unit) at 78 kelvin
and 1.0 weight percent at room temperature and pressure of 20 bar. Inelastic
neutron scattering spectroscopy of the rotational transitions of the adsorbed
hydrogen molecules indicates the presence of two well-defined binding sites
(termed I and II), which we associate with hydrogen binding to zinc and the
BDC linker, respectively. Preliminary studies on topologically similar
isoreticular metal-organic framework-6 and -8 (IRMOF-6 and -8) having
cyclobutylbenzene and naphthalene linkers, respectively, gave approximately
double and quadruple (2.0 weight percent) the uptake found for MOF-5 at room
temperature and 10 bar."
