COPPER(II) AND SILVER(II) COMPLEXES OF POLYMER-BOUND PORPHYRINS WITH SCHIFF-BASE LINKAGE

Two percent divinylbenzene (DVB)-crosslinked polystyrene was prepared and functionalized to obtain its aldehyde analog. Amino porphyrins wer e anchored on this polymer support by Schiff base condensation. The an choring positions were adjusted so as to obtain ortho-, meta-, and par a-isomeric systems. The polymer-bound free-base porphyrins were metall ated to obtain the corresponding Cu(II) and Ag(II) complexes by treati ng them with the corresponding metal salt solutions. The products were characterized chemically and spectroscopically. Electronic and ESR sp ectral analysis shows the microenvironmental participation of the poly mer network on the electronic levels of the porphyrin system. The exte nts of steric and electronic participation were evaluated and are pres ented. (C) 1998 John Wiley & Sons, Inc.
