合成了3个配体:N,N,N′,N′, 四(2 羟乙基) 1,3 丙二胺(1),N,N,N′,N′, 四(2 羟乙基) 1,10 癸二胺(2),N,N,N′,N′, 四(2 羟乙基) 1,4 对甲苯二胺(3)及其与二价金属离子Zn(II)和Co(II)形成的金属配合物.在25℃,不同pH值下,研究了这些金属配合物在Brij35胶束溶液中催化PNPP水解的反应.其结果表明:在催化PNPP水解反应中,其活性物种为2∶1(配体:金属离子)的单核金属配合物.不同金属配合物的催化活性与配合物的桥联配体及反应的微环境相关.
Three ligands were synthesized: N, N, N ’, N’, tetrakis (2hydroxyethyl) 1,3 propanediamine (1) (2), N, N, N ’, N’, tetrakis (2 hydroxyethyl) 1,4-toluylenediamine (3) and their complexes with divalent metal ions Zn Co (II) was synthesized.The reaction of these metal complexes catalyzing the hydrolysis of PNPP in Brij35 micelles solution was studied at different pH values at 25 ℃ .The results showed that in the catalytic PNPP hydrolysis reaction, the activity of these complexes The mononuclear metal complexes of species 2: 1 (ligand: metal ion) .The catalytic activity of different metal complexes is related to the ligands’ bridging ligands and the reaction microenvironment.
