Abstract:
An unusual porous metal-organic framework has been synthesized by using Pb(II) and rigid V-shaped 4,4'-(pyridine-3,5-diyl)diisophthalic acid (H4L). Structure analysis reveals that there exist 1D cylindrical 14.26 Å and triangular prism 10.69 × 10.69 × 10.69 Å3 nanotubes in the framework. Gas sorption behavior of the nanoporous MOF shows a relatively high capacity and selectivity of CO2 over CH4.
