Polysaccharide derivatives coating onto silica matrices represents nowadays one of the most popular chiral stationary phases (CSPs) and these kinds of phases are commercially available. However, the solubility of polysaccharide derivatives in a number of solvents limits the application range on the commercial chiral columns. This problem can be solved by chemically fixing polysaccharide derivatives onto silica matrices. On the one hand, atom transfer radical polymerization (ATRP) technique is very efficient for grafting from solid surfaces. In this study, we prepared cellulose phenyl carbamate derivatives-grafted silica particles from cellulose 2,3-bis(3,5-dimethylphenylcarbamate)-6-methacrylate and the initiator-grafted silica particle, which is synthesized from aminated silica gel and 2-bromoisobutyryl bromide, by atom transfer radical polymerization. |
