Abstract A series of mononuclear copper(II) complexes of the type [Cu(L)Cl2] 1–6, where L is a tridentate 3 N ligand such as N-methyl-N′-(pyrid-2-ylmethyl)ethylenediamine (L1), N-ethyl-N′-(pyrid-2-ylmethyl)ethylenediamine (L2), N-phenyl-N′-(pyrid-2-ylmethyl)ethylenediamine (L3), N,N-dimethyl-N′-(pyrid-2-ylmethyl)ethylenediamine (L4), N,N-diethyl-N′-(pyrid-2-ylmethyl)-ethylenediamine (L5) and N-met
摘要一系列[Cu(L)Cl2] 1–6型单核铜(II)配合物,其中L是三齿3 N配体,例如N-甲基-N'-(吡啶-2-基甲基)乙二胺( L1),N-乙基-N'-(吡啶-2-基甲基)乙二胺(L2),N-苯基-N'-(吡啶-2-基甲基)乙二胺(L3),N,N-二甲基-N'- (吡啶-2-基甲基)乙二胺(L4),N,N-二乙基-N'-(吡啶-2-基甲基)乙二胺(L5)和N-甲基-N'-(吡啶-2-基甲基)苯- 1,2-二胺(L6)已被分离出来,并作为不同含水胶束介质中邻苯二酚氧化酶的功能模型进行了研究。2和5的X射线晶体结构包含CuN3Cl2发色团,该发色团具有基于三角形双锥体的配位几何形状。有趣的是,所有配合物都形成阳离子型[Cu(L)(DBC)(H2O)] +加合物,其中DBC2-作为单齿配体,加合物与阴离子SDS胶束强烈相互作用。加氧酶的反应速率遵循SDS> TX-100〜水> CTAB的
