Abstract:
 Molecular motion of methanol adsorbed in 1D nano-channels of pillared-
layer coordination polymer with paramagnetic metal ion have been studied 
by 2H NMR together with X-ray crystallography.
 We report high levels of selective sorption of acetylene molecules as compared 
to a very similar molecules, carbon dioxide, onto the functionalized surface of
a MOM. The astylene molecules are held at a periodic distance from one another by
hydrogen bonding  between two non-coordinated oxygen aotms in the nanoscale pore 
wall of the MOM and the two hydrogen atoms of the acetylene molecule. This permits 
the stables storages of scetylene at a density 200 times the safe compression limit 
of free acetylene at room temperatere.
