Synthesis, Self-Assembling Properties, and Atom Transfer Radical Polymerization of an AlkylatedL-Phenylalanine-Derived Monomeric Organogel from Silica: A New Approach To Prepare Packing Materials for High-Performance Liquid Chromatography
aggregation by van der Waals interactions. Compound 4 was polymerized by surface-initiated atomtransferradicalpolymerizationfrom porous silica gel to prepare a packingmaterial for HPLC. The results of thermogravimetric analysis showed that a relatively large amount of polymer was grafted onto the silica surface. The organic phase on silica was in a noncrystalline solid form in which the long alkyl
