3-D pillared clay mimics of lanthanide–organic frameworks constructed from 5-fluoroisophthalic acid and 4,4′-bipyridine through hydrogen bonds

Four 2-D lanthanide coordination polymers constructed from 5-fluoroisophthalic acid show reliable 3-D pillared clay mimics based on the secondary hydrogen-bonding with 4,4′-bipyridine templates. The dimensionality of the structures turns out to be independent of the ionic radius of the lanthanide centers and the EuIII complex displays strong red luminescence.
