Phosphinic Acid Based Linkers: New Building Block in MOF Chemistry

Jan Hynek, Jan Rohlíček, Jan Demel, Petr Brázda, Michael G.S. Londesborough
Metal-organic frameworks (MOFs) are a chemically and topologically diverse family of materials composed of inorganic nodes and organic linkers bound together by coordination bonds. In this contribution we present two significant innovations in this field. The first is the use of a new coordination group in phenylene-1,4-bis(methylphosphinic acid) (PBPA), a phosphinic acid analogue of commonly-used terephtalic acid. We show that the use of this new linker group leads to the formation of a hydrothermally stable permanently porous MOF structure. The second innovation is the application of electron diffraction tomography (EDT), coupled with dynamical refinement of the EDT data, to the elucidation of the structure of the new material including the localization of hydrogen atoms.
