英文摘要	a number of half-salen aluminum complexes bearing unsymmetrical [onn]-type ligands were prepared from tridentate dinaphthalene-imine derivatives. these complexes were characterized by h-1 and c-13 nmr spectroscopy, elemental analysis and single crystal x-ray diffraction analysis. these complexes were employed for rac-lactide and l-lactide polymerization. upon activation with isopropanol, complex (s)-b-6 (r-1 = r-2 = r-4 = h; r-3 = f) showed the highest activity (a monomer conversion of 94.6%) amid these aluminum complexes for the ring-opening polymerization of l-lactide; and complex (s)-b-2 (r-1 = r-2 = r-3 = h; r-4 = bu-t) showed the highest stereoselectivity for the ring-opening polymerization of rac-lactide, obtaining a polylactide (pla) with a pm of 0.69. the polymerization kinetics utilizing (s)-b-6 as a catalyst were researched in detail. the data on the polymerization kinetics revealed that the rate of polymerization was first-order with respect to the monomer and the catalyst. there was a linear relationship between the l-lactide conversion and the number-average molecular weight of pla.
