| Popis: | 105 A series of Al and Zn complexes bearing N, O-Schiff base ligands was synthesized and their application for the ring-opening polymerization of ε-caprolactone was studies. Recently, most studies have focused on the six-membered ring Al and Zn complexes bearing N, O-Schiff base ligand. However, no study has been reported about five-membered ring complexes. In the structure, unlike the six-membered ring complexes, the five-membered ring complexes expose more metal space in environment, and have higher activity in comparison with corresponding six-membered ring complexes. Therefore, a series of aluminum complexes bearing N, O-Schiff base ligands were prepared the comparison of catalytic behavior between five and six-membered ring aluminum and zinc complexes bearing Schiff base ligands for the ROP of ε-CL and L-Lactide in detail. |
