A New Route for Preparation of High-density Organic Phase to High Selective HPLC for Polycyclic Aromatic Hydrocarbons by Atom-transfer Radical Polymerization of Octadecyl Acrylate on Silica

We have previously reported that poly(octadecyl acrylate) as an organic stationary phase in HPLC shows high molecular-shape selectivity through carbonyl–π interaction on highly ordered structures of long alkyl chains. In this communication, a new “grafting-from” strategy based on surface-initiated a...

Description
Summary:We have previously reported that poly(octadecyl acrylate) as an organic stationary phase in HPLC shows high molecular-shape selectivity through carbonyl–π interaction on highly ordered structures of long alkyl chains. In this communication, a new “grafting-from” strategy based on surface-initiated atom-transfer radical polymerization is applied for ordering of poly(octadecyl acrylate) on silica to lead to remarkable selectivity increase.
