Abstract
Sequential wholly aromatic polyketone 5, where 2,2′-dimethoxybiphenylene units and m,p-diphenylenedicarbonyl ones align alternately, was successfully synthesized via finely tuned designings of the structure and synthetic protocol for arenecarboxylic acid monomer (6). Different from the 2,2′-dimethoxybiphenylene-containing wholly aromatic polyketones (1–4) reported recently, the polyketone (5), the conjugated macromolecule composed of regiochemically sequenced arene and carbonyl moieties, is soluble in organic solvents.
