Summary: | 碩士 === 國立中興大學 === 化學系所 === 104 === A series of imidazole-phenolate and bis-imidazole-phenolate ligand
precursors R1-R3 and 2R1-2R3,[R1 = HOPhMeImph;R2 = HOPhMeImH;R3 = HOPhMeImMe ;2R1 = HOPhMebis-Imph ;2R2 = HOPhMebis-ImH;2R3 = HOPhMebis-ImMe] have been discovered. These ligand precursors can react with trimethyl aluminum to make complexes 14-18. Complexes 14-18 show good activity and low PDI toward ε-caprolactone ring-opening polymerization with 9-AnOH. The complex 16 shows good activity toward 100 and 200-fold concentrationε-caprolactone,but it shows less control when the concentration of ε-caprolactone reaches 300-fold. The complex 16 and 17 show activity towardε-caprolactone ring-opening polymerization without adding alcohol,while the molecular weight and PDI are much higher than respect.
