chitosan attached ferrocene were prepared by reacting of poly-(1,4-β-d -glucopranosamin) (chitosan, low molecular weight, Sigma-Aldrich) (2 g) in hot C2H5OH (60 mL) with ferrocene aldehyde (2.14 × 102 mol) in C2H5OH (15 mL) (Fig. 1B ).
Aldehyde solution was slowly added by the dropwise on chitosan solution while stirring through 30 min. Then the reaction mixture was boiled and stirred under a reflux condenser ca. 6 h, at 60 °C.
After the mixture cooling to room temperature, chitosan attached ferrocene precipitated and washed by adding acetone. The resulting clear yellow product was filtered and dried in the oven at 80 °C.
