合成了丙二硫醚桥联2个乙酰丙酮的双β-二酮分子1,3-二(3-硫醚基-2,4-戊二酮基)丙烷(L1),以此为配体与镍(Ⅱ)作用得到配合物,通过元素分析和摩尔电导分析方法确定了镍(Ⅱ)配合物的化学组成,比较分析了配位前后的游离配体与配合物的红外及紫外吸收光谱,采用紫外光谱滴定法对配体L1与Ni(Ⅱ)离子在溶液中的配位行为进行了模拟研究,并进行金属离子液膜传输实验考察了L1对Ni(Ⅱ)的液膜传输性能。结果显示,L1通过4个O原子与Ni(Ⅱ)配位成键形成配合物,且对Ni(Ⅱ)具有良好的液膜传输性。

The bis-β-diketone molecule incorporating 1,3-propanedithioether bridge between the γ-carbons of respective β-diketone units of 1,3-bis(3-thio-2,4-pentanedionate)propane(L1)had been synthesized,and then L1as a ligand reacted with Ni(Ⅱ)to form a nickel complex. The formula of Ni(Ⅱ) complex was determined by elemental analysis and molar conductance. The possible coor-dination mode of complex were concluded by comparison with the IR&UV spectral properties of the free ligand and its nickel(Ⅱ) complex. Additionally,the coordination behavior of nickel salts and bis-β-diketone ligand L1 in solutions and the liquid membrane transport property of L1 with Ni(Ⅱ) ion were also investigated by ultraviolet spectroscopy characterisation. The results showed that bis-β-diketone ligand L1 coordinate through four oxygen atoms bonding Ni(Ⅱ) ,and L1 had a good liquid membrane transport prop-erty for nickel(Ⅱ) ion.
