✦ Synopsis

The modi5cation of the internal pore surface of mesoporous MCM-41 with 3-aminopropyl yielded amine group functionalized MCM-41. Copper(II) and manganese(II) phenanthroline complexes were grafted onto the functional MCM-41 via the coordination of the respective metal ion with the amine group. The metal ion complex functionalized mesoporous materials were characterized by powder X-ray di4raction (XRD), nitrogen adsorption/desorption at 77 K, solid state di4use re6ectance UV spectroscopy, and electron spin resonance (ESR) at 293 K as well as cyclic voltammetry. Preliminary studies suggested that the nature and electroactivity of metal ion complex functionalized MCM-41 di4ered signi5cantly from those of metal ion complex impregnated MCM-41.

Square pyramidal copper(II) complexes with second-generation fluoroquinolone, pefloxacin and phenanthroline derivatives were prepared and characterized. They were also screened for in-vitro activity against two Gram (+ve) and three Gram (-ve) microorganisms. SOD mimic behavior was actively sought fo
