摘要：

A series of pyridine and polypyridine-zinc complexes were synthesized, and their application in epsilon-caprolactone and L-lactide polymerization was studied. In epsilon-caprolactone polymerization, zinc complexes bearing 1,10-phenanthroline derivatives exhibited a higher polymerization rate than did diethyl zinc (2-10 times). In L-lactide polymerization, zinc complexes bearing 1,10-phenanthroline derivatives exhibited a considerably higher polymerization rate than did diethyl zinc (2-220 times). According to density functional theory results, the orthohydrogens of polypyridine ligand can co-activate the carbonyl group of monomers with zinc metal center to increase the catalytic activity of zinc catalysts.
