Abstract
Branched carboxylated polyphenylquinoxalines are prepared via the interaction of tris(α-diketone), 4,4′-bis(phenylglyoxalyl)benzyl, with an equimolar amount of 3,4-diaminobenzoic acid and subsequent interaction of the reaction product with an equimolar amount of bis(o-phenylenediamines). Polymeranalogous transformations of these polymers with 1-amino-8-naphthol-3,6-disulfonic acid sodium salt monohydrate in Eaton’s reagent yield earlier undescribed branched polyphenylquinoxalines containing side naphthoxazine-5,8-disulfonic acid groups.
