报道了三齿配体N,N-二[2′-苯并咪唑甲基]亚胺(IDB)的含铜(Ⅱ)配合物的合成和表征,用硝基蓝四氮唑(NBT)光还原法测得该系列模型化合物与O_2~-反应速率常数在10~6~10~8mol~(-1)·L·s~(-1),根据电导和UV-Vis,IR和ESR谱,推测该系列配合物中Cu(Ⅱ)离子可能为典型的四方锥或八面体配位。首次发现该系列含Cu(Ⅱ)配合物冻结DMF溶液X波段的ESR谱在1500G附近有半场峰,表明这些单核配合物在溶液中存在核间的抗铁磁场性偶合。它们均具有极好的水、脂兼溶性和优良的超氧化物歧化酶(SOD)活性(以每摩尔Cu(Ⅱ)计)。
The synthesis and characterization of copper (Ⅱ) complexes containing tridentate ligand N, N-bis [2’-benzimidazolylmethyl] imide (IDB) have been reported. Nitroblue tetrazolium According to the conductance and UV-Vis, IR and ESR spectra of the model compounds and the reaction rate constant of O 2 - in the range of 10 ~ 6 ~ 10 ~ 8 mol -1 L · s -1, It is speculated that the Cu (Ⅱ) ions in this series of complexes may be typical tetragonal or octahedral coordination. For the first time, it was found that the ESR spectrum of X-band of the frozen DMF solution containing Cu (Ⅱ) complexes has a half-peak at around 1500G, indicating that these mononuclear complexes exist anti-ferromagnetic coupling in solution. They all have excellent water, fat and solubility and excellent SOD activity (per mol Cu (II)).
