Abstract
The present invention relates to porphyrins and to metal ion-containing monomers and polymers. The monomer ##STR1## wherein A, R.sup.1,R.sup.2,R.sup.3, and R.sup.4 defined herein, is used with dianhydride to produce a porphyrin polymer or a metal ion containing porphyrin polymer. These polymers are useful as electrical conductors and as liquid crystal polymers, non-linear (NLO) materials, magnetic materials, electrochromic polymers photo-and electrocatalysts and advanced materials.
