A highly porous three-dimensional aluminum phosphonate with hexagonal channels: synthesis, structure and adsorption properties.

ABSTRACT

A 3D porous aluminum(III) trisphosphonate, constructed from 1D inorganic aluminum phosphate chains and tripodal organic linkers, contains large hexagonal channels (1.24 nm in diameter) and a highly accessible void (50.3%) which allow it to have a fast and relatively high uptake of H2, N2 and CO2.
