英文摘要	four hemi-salen aluminum complexes based on tridentate n, n, o-type binaphthyl-schiff-base derivatives (1: r = pr-i; r-1 = h; 2: r = pr-i; r-1 = cl; 3: r = 2-adamantyl; r-1 = h; 4: r = 2-adamantyl; r-1 = bu-t) were prepared. these complexes were characterized by h-1, c-13 nmr spectroscopy and elemental analysis, these four complexes were employed for ring-opening polymerisation of l-lactide and rac-lactide. complex 2, which was based on pro-ligand l-2 with smaller steric hindrance and electron-withdrawing substituents, displayed the highest activity for rop of l-lactide among these complexes, and complex 4, which was supported by pro-ligand l-4 with the biggest steric hindrance, showed the highest stereoselectivity for the rop of rac-lactide with partially isotactic polylactide with a p-m of 0.65. kinetic studies revealed the rop of l-lactide initiated by complex 3 had first-order dependency on [la] as well as [al].
