合成了双水杨醛缩二甘醇二胺（ＳＡＬＤＡ） 及双水杨醛缩四甘醇二胺（ＳＡＬＴＴＡ） 两类直链醚型Ｓｃｈｉｆｆ 碱，并用于合成钴、镍的四种Ｓｃｈｉｆｆ 碱配合物，经分析，其组成为［ Ｍ（ＳＡＬＤＡ）］（ＮＯ３）２·Ｈ２Ｏ 和［ Ｍ（ＳＡＬＴＴＡ）］（ＮＯ３）２·ｎＨ２Ｏ，并以热重—差热分析、紫外、红外光谱以及核磁共振谱等方法研究了它们的配位作用．此类配合物能有效清除超氧阴离子自由基，具有明显的生物活性，并对甲基丙烯酸甲酯（ ＭＭＡ） 聚合有催化效果，转化率～７０ ％ ，分子量峰值可达１００万．
Two kinds of linear Schiff bases, SALDA and SALTTA, were synthesized and used to synthesize four Schiff base complexes of cobalt and nickel The results showed that the composition of [M (SALDA)] (NO3) 2 · H2O and [M (SALTTA)] (NO3) 2 · nH2O were determined by TG-DTA and UV-Vis and NMR Spectrum and other methods to study their coordination role. These complexes can effectively scavenge superoxide anion radical, have obvious biological activity, and catalyze the polymerization of methyl methacrylate (MMA) with a conversion rate of ~ 70% and a peak molecular weight of up to 1 million.
