Here, we report a new synthetic protocol based on microwave-assisted synthesis (MAS) for the preparation of higher yields of zinc and copper in MOFs based on different bis(pyrazolyl)-tagged ligands ([M(BPZ)]n where M = Zn(II), Cu(II), H2BPZ = 4,4′-bipyrazole, [M(BPZ-NH2)]n where M = Zn(II), Cu(II); H2BPZ-NH2 = 3-amino-4,4′-bipyrazole, and [Mx(Me4BPZPh)] where M = Zn(II), x = 1; Cu(II), x = 2; H2Me4BPZPh
在这里,我们报告了一种基于微波辅助合成(MAS)的新合成方案,用于在基于不同双(吡唑基)标记配体([M(BPZ)]n的MOF中制备更高产率的锌和铜,其中M = Zn(II)、Cu(II)、H2BPZ = 4,4′-联吡唑、[M(BPZ-NH2)]n 其中 M = Zn(II)、Cu(II);H2BPZ-NH2 = 3-氨基-4 ,4′-联吡唑和 [Mx(Me4BPZPh)] 其中 M = Zn(II), x = 1;Cu(II), x = 2;H2Me4BPZPh = 双-4′-(3′,5′-二甲基) -吡唑基苯),并首次对其抗菌活性进行了详细研究,针对作为感染代表的革兰氏阴性(大肠杆菌)和革兰氏阳性(金黄色葡萄球菌)细菌进行了测试。结果表明,所有 MOF 都具有广谱活性和高效抑制细菌生长的作用,其作用机制基于 MOF 颗粒通过所谓的“螯合效应”和活性氧与细菌细胞的表面接触。 ROS)生成,且没有大量释放
