Abstract
In this paper, we use chitosan as template molecule and N-[2-(dimethylamino) ethyl]-N’-[(2-hydroxy-4-vinylphenyl)] oxamide (H3eoxdmpe) as bridge ligand and directionally synthesize N-[2-(dimethylamino) ethyl]-N’-[(2-hydroxy-4-vinylphenyl)] oxamide dinuclear zinc-chitosan [Zn2 (eoxdmpe) (tetrachit)] (ClO4) coordination monomer. We study the interaction between complex and template molecules by ultraviolet spectrophotometry and the recognition ability of complex to monosaccharide molecule quantitatively by formula. The crystal structures of N-[2-(dimethylamino) ethyl]-N’-(2-hydroxy-4-vinylphenyl)] oxamide binuclear zinc-chitosan complex are determined and analyzed by X-ray single crystal diffractive technique and the results show that the metal coordination bond is a favorable binding activity for chitosan. This study provides an ideal model for the construction of metal coordination molecularly imprinted polymers which are selectively recognized by chitosan.
