In situ production of silver nanoparticles on an aldehyde-equipped conjugated porous polymer and subsequent heterogeneous reduction of aromatic nitro groups at room temperature
A new class of core–shell magnetic gold nanocomposites is prepared in a raspberry‐like fashion by the controlled supramolecular host–guest assembly of γ‐cyclodextrins (γ‐CDs) and boron clusters. In this work, Cs2[closo‐B12H12], a fundamental boron cluster, can play a dual role in the preparation of highly monodispersed Au nanoparticles and in the immobilization of Au nanoparticles on the γ‐CDs@Fe3O4
通过控制γ-环糊精(γ-CDs)和硼团簇的超分子主体-客体组装,以覆盆子状的方式制备了新型的核-壳磁性金纳米复合材料。在这项工作中,基本的硼簇Cs 2 [ closo- B 12 H 12 ]可以在制备高度单分散的Au纳米颗粒以及将Au纳米颗粒固定在γ-CDs@ Fe 3 O 4上起双重作用。表面作为有效的锚点。这种简便而自发的超分子策略可以控制高度稳定的金复合材料的尺寸和组成。此外,获得的AuNPs @ Fe 3 O 4 复合材料具有优异的催化活性和可再循环性,可将硝基芳族化合物选择性还原为相应的苯胺化合物,并且在20 s内即可实现最快的反应,并且在室温下具有较高的转化率和选择性,这比之前在SiO2研究中获得的要好。金属纳米颗粒复合材料作为催化剂。

Synthesis of new 3-phenylquinazolin-4(3H)-one derivatives as potent antibacterial agents effective against methicillin- and vancomycin-resistant Staphylococcus aureus (MRSA and VRSA)
infections due to the drug resistant Staphylococcus aureus is on rise necessitating the need for rapid development of new antibacterialagents. In our present work, a series of new 3-phenylquinazolin-4(3H)-one derivatives were designed, synthesized and evaluated for their antibacterial activity against ESKAP (E. coli, S. aureus, K. pneumoniae, A. baumannii, P. aeroginosa) pathogen panel and pathogenic mycobacterial
