he present study evaluates the cooperative effects of dendronized chitosan microbeads with tris- and hexa-functionalizeddendrons for capturing copper and for further use as catalysts. The dendronized microbeads were characterized by infraredspectroscopy, scanning electron microscopy, thermogravimetry, swelling capacity analysis, and atomic absorptionspectroscopy. A correlation between the number and type of functional groups at the dendritic surface of the dendronizedmicrobeads and the retention of copper highlights structural features of the cooperative effect. It is demonstrated thatcovalently bound dendrons can modulate the properties of chitosan, which has shown potential as a catalyst for thedevelopment of a novel materials.
