AbstractCobalt 2,4-dinitrophenolate (complex 1) based upon a N,N,O,O-tetradentate Schiff base ligand framework was prepared. X-ray diffraction analysis confirmed that complex 1 was triclinic species with a six-coordinated central cobalt octahedron in the solid. Asymmetric alternating copolymerization of carbon dioxide (CO(2)) with racemic propylene oxide (rac-PO) proceeded effectively by complex 1 in conjunction with (4-dimethylamino)pyridine (DMAP), yielding a perfectly alternating and bimodal molecular weight distribution PO/CO(2) poly(propylene carbonate) (PPC) with a small amount of cyclic carbonate byproducts.
