Synthesis of polyesters containing 9,10-diacetoxyanthracene-2,6-diyl moieties via a precursor polymer approach

Abstract

Soluble polyesters are synthesised by polymerising a range of bis(acid chloride)s with the bisphenol that is formally the Diels–Alder adduct of 9,10-diacetoxy-2,6-dihydroxyanthracene and dimethyl maleate. Heating the soluble polyesters to about 230 °C brought about retro-Diels–Alder reactions to give the insoluble target polyesters containing 9,10-diacetoxyanthracene residues.
