采用季胺基取代的水杨醛(由2,4-二羟基水杨醛、1,2-二溴乙烷、高氯酸钠等为原料合成)合成了两个新型Salen配体N,N'-二{4-[[2-(三甲胺基)乙基]氧化]水杨醛}-邻苯二胺二高氯酸盐(L1), N-(2-羟基-5-甲基二苯甲基)-N'-{4-[[2-(三甲胺基)乙基]氧化]水杨醛}-邻苯二胺高氯酸盐(L2), 并进一步合成了8个新型Salen金属配合物[ZnL1, NiL1, CuL1, ZnL2, NiL2, CuL2, MnL2, CoL2]. 用1H NMR, 13C NMR, FT-IR, UV-vis, MS对配体和配合物进行了表征, 测定了金属配合物的水溶性及在水中的摩尔电导率. 结果表明, 与相应母体配合物的水溶性比较, 含有季胺基修饰的Salen金属配合物的水溶性有了较大提高.

关键词: 新型Salen配合物, 合成表征, 谱学性质, 摩尔电导率, 水溶性

Two novel salen ligands, N,N¢-bis[4-[[2-(trimethylammonio)ethyl]oxy]salicylidene]-o-phenyldia- mine diperchlorate (L1) and N-[(2-hydroxy-5-methyldibenzophenyl)methyl]-N¢-[4-[[2-(trimethylammonio)- ethyl]oxy]salicylidene]-o-phenyldiamine perchlorate (L2), and their metal complexes (ZnL1, NiL1, CuL1, ZnL2, NiL2, CuL2, MnL2 and CoL2) were synthesized and characterized by 1H NMR, 13C NMR, FT-IR, UV-vis, MS etc. Molar conductance of the eight metal complexes in water was measured. Water-solubility of the metal salen complexes is much higher than that of their parent complexes.

Key words: novel salen complex, synthesis, characterization, spectral property, molar conductance, water-solubility
