Abstract

An ultrasonication technique has been used to synthesize a Co(II)-metallogel using isophthalic acid as a gelator and cobalt(II)-acetate in N,N-dimethylformamide at room temperature. Rheological analysis revealed its robust mechanical properties, while FESEM and EDX mapping provided insights into its microstructure and elemental composition. FT-IR spectroscopy elucidated the mechanism of metallogel formation. Optical absorption studies indicated a semiconducting nature, with the material exhibiting a significantly higher electron mobility than similar compounds. The Co(II)-metallogel demonstrated strong antimicrobial activity against both Gram-positive (Bacillus subtilis and Staphylococcus epidermidis) and Gram-negative (Escherichia coli and Pseudomonas aeruginosa) bacteria. These findings highlight the metallogel’s dual potential in electronics due to its superior semiconducting properties and in biomedicine, owing to its broad-spectrum antibacterial effects.

用于抗菌和半导体微电子器件的生物活性超分子钴(II)-金属凝胶的研制

以异苯二甲酸为凝胶剂，在N，N-二甲基甲酰胺中，采用超声法制备了Co(II)-金属凝胶。流变学分析揭示了其强大的力学性能，而FESEM和EDX图谱则揭示了其微观结构和元素组成。红外光谱分析阐明了金属凝胶的形成机理。光学吸收研究表明，该材料具有半导体性质，其电子迁移率明显高于类似化合物。Co(II)-金属凝胶对革兰氏阳性菌（枯草芽孢杆菌和表皮葡萄球菌）和革兰氏阴性菌（大肠杆菌和铜绿假单胞菌）均有较强的抗菌活性。这些发现突出了金属凝胶在电子学方面的双重潜力，因为它具有优异的半导体特性，而在生物医学方面，由于它具有广谱的抗菌作用。
