Thermal polymerization of bis(4-fluoro-2,6-dibromophenolato)bis(pyridine)copper(II) complex in solution and in solid state

摘要

The synthesis of the bis(4-fluoro-2,6-dibromophenolato)bis(pyridine)copper(II) complex was achieved from aqueous solution, and its characterization was performed by means-of IR and CHN elemental analysis. Thermal polymerization of this complex was carried out in toluene and in solid state. The structural analysis of the polymers was performed with H-1 NMR, C-13 NMR and FTIR analysis; the glass transition temperature was found to be at 160 degrees C. 4-Fluoro-2,6-dibromophenolate, with the non-chelating ligand pyridine, displays selectivity in favor of 1,2-catenation.
