Exploring (bio)catalytic activities of structurally characterised Cu(ii) and Mn(iii) complexes: histidine recognition and photocatalytic application of Cu(ii) complex and derived CuO nano-cubes

Abstract

Structurally characterised two polymeric complexes of Cu(II) (3) and Mn(III) (4) of the ligand L (2-(((2-(phenylamino)ethyl)imino)methyl)phenol) have been explored for catecholase-like activity, fluorescence recognition of histidine and catalytic activity towards coupling of aryl iodides with benzamide, leading to N-arylbenzamides. CuO nano-cubes (NCs) prepared by thermal decomposition of the Cu(II) complex function as photocatalysts for the degradation of methylene blue. Cube-like morphology of CuO nanocrystal and flake-shaped micrometer order Cu(II) complex have been established from the field emissive scanning electron microscopy (FESEM) images.
