直链醚型Schiff碱与钴(Ⅱ)、镍(Ⅱ)配合物的合成、表征及其活性的研究

SYNTHESIS AND CATALYTIC ACTIVITY OF NONCYCLIC POLYETHER SCHIFF BASE COMPLEXES OF COBALT(Ⅱ) AND NICKEL(Ⅱ)

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 noncyclic polyether Schiff bases condensed from salicylic aldehyde and diethylene or tetraethylene glycol diamine have been obtained. Four complexes of these Schiff bases with Co(Ⅱ) or Ni(Ⅱ) nitrates have been synthesized and characterized by IR,UV,\+1H NMR respectively. The experimental results proved that both of the obtained complexes had scavenging effect on superoxide anion free radical and showed catalytic activities in the polymerization of methyl methacrylate as well. \;
