Hybrid Composites of Hydrogels of Natural Cellulose with Electron-Excess Binuclear Zn(II) 1,10-Phenanthrocyanine. Immobilization of the Zinc Complexes in Cellulose Hydrgels and the Functional Composition of the Resultant Compounds

Abstract

New composites are obtained in the diffusion-adsorption immobilization of electron-excess zinc(II) 1,10-phenanthrocyanine complexes [(phen)nZn(μ-phencyanine)Zn(phen)n(OAc)4∙HOAc] (n = 0-2) in a 3D structure of super-swelling cellulose hydrogels. A mechanism is proposed for the immobilization of the zinc complexes in the hydrogel structure. The functional and chemical composition of the composites was studied in detail using Fourier transform IR spectroscopy. The immobilization of the complexes in the hydrogels structure was found to lead to their chemical reaction with cellulose in the hydrogel matrix.
