Herein we reported the synthesis of Schiff base ligand and their complexes (1–5) with copper (II) metal ion and aromatic diimines. The Schiff base derived from the condensation of 2, 6- diisopropylaniline and 5- chlorosalicylaldehyde.The Schiff base ligand and their complexes (1–5) have been characterized by microanalysis, molar conductance, room temperature magnetic susceptibility, FT – IR, UV–visible, Cyclic voltammetry and mass spectroscopy techniques. Their low electrical conductance values indicate that the complexe 1 is non electrolyte and remaining other complexes 2-5 are in electrolyte nature. The monomeric nature of the complexes is evidenced from their magnetic susceptibility values. The electronic spectra of the complexes suggest that they have distorted octahedral geometry around the metal ion. The electrochemical behavior, the anodic and cathodic peak potential and the number of electron transfer have been calculated by using cyclic voltammetry. These synthesized complexes have been tested against micro-organisms such as S. aureus, B. bacillus (Gram – positive) and E. coli, P. aeruginosa (Gram – negative) bacterial strains with known antibacterial and antifungal drugs (amoxyclav and oxiconazole).

含4-氯-2- [2,6-二异丙基苯基亚氨基)甲基]苯酚席夫碱配体和芳族二亚胺的铜(II)配合物的合成,表征,生物学和电化学研究

在本文中,我们报道了席夫碱配体及其与铜(II)金属离子和芳族二亚胺的配合物(1-5)的合成。Schiff碱衍生自2,6-二异丙基苯胺和5-氯水杨醛的缩合。Schiff碱配体及其配合物(1-5)的特征在于微分析,摩尔电导,室温磁化率,FT-IR,UV-可见光,循环伏安法和质谱技术。它们的低电导率值表明配合物1是非电解质,其余的配合物2-5具有电解质性质。配合物的单体性质从其磁化率值得到证明。配合物的电子光谱表明,它们已经扭曲了金属离子周围的八面体几何形状。电化学行为 使用循环伏安法计算了阳极和阴极的峰值电势以及电子转移的次数。这些合成的复合物已通过已知的抗菌和抗真菌药物(阿莫克拉韦和奥昔康唑)针对金黄色葡萄球菌,芽孢杆菌(革兰氏阳性)和大肠杆菌,铜绿假单胞菌(革兰氏阴性)等细菌菌株进行了抗微生物测试。 。
