Rhodamine B oxidation promoted by P450-bioinspired Jacobsen catalysts/cellulose systems.

ABSTRACT: In this work, we investigated the preparation of P450-bioinspired Mn(iii)-Schiff base complexes supported on DEAE-cellulose ((R,R)-Jacobsen/Cell(NEt₂) and (S,S)-Jacobsen/Cell(NEt₂), respectively) to oxidize substrates of biological interest. Catalysts were characterized by several physical techniques. UV-Vis spectroscopy with diffuse reflectance (DR/UV-Vis) analysis featured peculiar electronic transitions for both complexes. Fourier transform infrared (FTIR) spectra evidenced the characteristic band of imine groups (HC[double bond, length as m-dash]N) for bioinspired/Cell(NEt₂) materials. Immobilization ratios in cellulose fibres were confirmed by atomic absorption spectroscopic (GF-AAS) analyses. Catalytic essays were conducted
