Preparation of complexes between dibenzo-18-crown-6 and primary aromatic amine picrates

Written by sctunisie no comments

Artificial ionophores interest in comprehension of mode transport of ions in natural medium induced us to use dibenzo-18-crown-6 as ionophore and to use its complexation by ammonium ions as simple models of amino-acids. A series of non commercial picrates of aromatic amines was prepared and characterized by elemental analysis and by spectroscopy. Picrates are afterwards complexed by the benzenic crown using one Pedersen's modified method. We have synthesized and characterized new stable crystalline complexes for a next structural study.
