EPR INVESTIGATION OF THE COORDINATION STRUCTURES OF CU(II) COMPLEXES OF DIVINYLBENZENE-CROSS-LINKED POLY(N-2-AMINOETHYLACRYLAMIDE)S

EPR spectra were used to follow the coordination of Cu(II) to amino fu nctions supported on DVB-crosslinked polyacrylamines. The dependence o f the extent of rigid divinylbenzene (DVB)-crosslinking on the incorpo ration of amino function, Cu(II) intake and the coordination geometry and the covalent character of the Cu-N bond was followed. The structur e of the Cu(II) complex has a distorted tetragonal geometry and the co valency of the Cu-N bond varies with the extent of the rigid DVB-cross linking in the polyacrylamide support.
