| 英文摘要 | A synthetic method for a new unsymmetrical Schiff base and its Ln(Ill) complexes including multi C = N- groups is reported. The complexes are characterized by elemental analysis, IR spectra, H-1 and C-13 NMR, especially 2D-COSY H-1, H-1 NMR spectra. The general formula of the obtained complexes is [Ln(3)(TBLY)(NO3)(3)] . nH(2)O (Ln = La, n = 3; Ln = Nd, n = 5; Ln = Gd, Dy, Yb, Y, n = 7), where TBLY = tetraglycol aldehyde-2,4-dihydroxy benzaldehyde bis-lysine Schiff base. In addition, the evidence for existence of C = CH-NH- group is supported by the AM1 method. The complexes obtained may be used as a catalyst. Conversion rate of 80% with the viscosity-average molecular weight 220000 for the polymerization of methyl methacrylate (MMA) without addition of any cocatalyst has been obtained. |
