Studies on Polymer Supported Copper Complexes: A Comparison of EPR Data.

Abstract

2 percent divinyl benzene (DVB) crosslinked polystyrene support was
synthesized by suspension copolymerization technique and functionalized
to get chloromethyl function.  A series of ligands were anchored on to the
polymer support by suitable chemical modifications. The ligands selected
were Schiff bases, ethylene diamine and dithiocarbamates. The polymeric
ligands were complexed with copper by simple chemical reactions. SS,
NN, NO and OO donor sites form copper complexes with differing spectral
and magnetic propeities. The complexes were characterized by IR, UV-Vis
and EPR studies.  By varying copper environment, EPR parameters were
measured and analyzed systematically. The structure, geometry dnd chemical
properties of these complexes were studied from the spectral results.
