ABSTRACT
We proved the ability of bismethonium congeners to phase out selectively (100% yield, 100% recovery) the complementary partner from a solution containing equivalent amounts of the homologues α,ω-diiodoperfluoroalkanes. This applied also to complex industrial mixtures with very long diiodoperfluorocarbons (m = 8-16). Powder diffraction analysis demonstrated that the matching supramolecular adducts form also through a gas-solid reaction starting from the more volatile diiodoperfluorocarbons.
